Kenwood DNN990HD - Android 4.0.4 car stereo - How to get started with rooting? - MTCB Android Head Units Q&A

There is a new line of Kenwood car stereos ("DNN" series) including the DNN990HD and DNN790HD.
They are running Android and another thread suggests it's running the following version:
Code:
Kernal version
3.0.8-tcc

Build number
Binks_v8-userdebug 4.0.4 IMM76D eng.root.20130422 test-keys
How can I get started with trying to install the Play Store and/or root the device?
There are two female USB ports on the back but I don't think it has any other ports.
Should I purchase a USB male-to-male cable and try to connect both ports to my PC? ...and then run "adb devices" ?
Can anybody give me any other tips?

I did notice that there're is a 4 pin connector hidden under a clear plactic tab on the right side of the unit. It is either a J-tag or a proprietary USB connector. The older models with WindowsCE core had a 6 pin connector under the same plastic tab. I have a feeling that's a clue to adb access. On a side note, I tried almosst every possible button press/hold combo upon reset/boot to try to find recovery with no success. And while the android version is build 8 the Kenwood build is version is 1.0. I have a feeling that the only other way in will involve modifying an update file.

Thanks for the information!
Do you have a picture of the connector?
USB is 4 pins so maybe it's just a different connector on one side of the cable? (to prevent people from "easily" plugging in a USB A-to-B cable)
...or maybe it's a serial port requiring a USB-to-RS232 cable? (like what is used to update the Metra Axxess ASWX-1 steering wheel adapter)

Here is a photo of the connector as well as a couple of other photos. If it is a rs232 like the flashlogic or xk loader, then it's essentially J-tag. Been a while since I did any J-tag modding though. I also tried plugging in the flashlogic/idatalink loader to the back plug and got nowhere as well. So far, I've found that you can plug in a usb keyboard and mouse for full easy control. I tried to use the browser for a file tree listing but it returns nothing. I was unable to figure out the mount path for the usb flash when connected, or I otherwise would have tried to run/install an apk directly. I also accessed gmail via the web window, changed the UA string for desktop, and tried to download an apk I sent myself with no luck, download showed up, but never started.

So I just downloaded the Google play store.apk file online (did a google search and downloaded the APK) and then uploaded the apk to my dropbox account. I then opened the browser in the DNN990HD and went to the dropbox.com website, logged in, and downloaded the apk file. It downloaded fine and I then launched it. I then got an error message saying "Install Blocked For security, your tablet is set to block installation of applications not obtained from Android Market."
Normally this is no big deal because you just go to applications and allow unknown sources to be installed on your device but Kenwood has hidden or gotten rid of that menu item so I can't access it. It looks like the next step is to figure out some sort of update.zip file but I haven't figured out if there's a way to get into the android bootloader on this thing.
Any other ideas out there yet?

I don't have anything to contribute, but I really, really hope some of the XDA guys can figure this out...

yeah this is a sweet radio, Installed it last weekend and love it,I used the Idatalink Maestro RR and i have all of my vehicle info on the radio screen it a sweet set-up, would be nice to install a regular gmail app and the play store, i`m wonder how much processor it has to run all of this stuff already. I wish I could figure out how to keep the Sirius replay off permanently.

Need to find a developer and probably enough donations raised to accomplish this.

I just put one of these in my car, it's pretty nice. I already noticed a force close on the launcher, lol. It only happened once I have since updated the BT firmware & software. What pisses me off it was suppose to have spotify support out of the box and I can't find any information on it really. I'm hoping this gets added with an update.I also wish they would have included OTA update support, you have to download it manually from kenwood & use a flashdrive.

DNN990HD Bluetooth Pairing
Has anyone had problems pairing their device with the DNN990HD? After installing the Kenwood firmware update I can't get the Pandora app on the head unit to connect to my Galaxy S4. Any suggestions would be appreciated.

So Could we maybe use this "USB UPDATE" method to gain install or root access?

I just installed one of these as well. Love it. I'd be willing to try almost anything to help get it rooted and have the Play store on it.

Okay guys I just tried editing the update for the radio by injecting the play story and a couple other apps I like into the update itself. The file structure is incredibly similar to a phone update. Unfortunately it did not go well. As it was updating it started to work but then the dead android icon appeared like a E: signature verification failed but it did not say that. I am only an amateur but it seems like we need a custom recovery or a way to adb either wired or maybe by wifi? I'm here to learn too so please any input would help.

Looking for hack into DNN 990 also... plus bluetooth issues...
LOL glad to see my favorite forums are on the DNN990 mission! Any progress on full access/root?
As well, I am having issues using bluetooth media with the device. The phone option works great (although it took several attempts to pair - those having trouble with this might like to know the unit won't pair if you have media source set to Pandora). The problem I'm having is with Ankidroid - I can't get the unit to broadcast my flashcards using text-to-speech, even though my present setup works on other hands-free devices. I tried playing audio file over bluetooth as well and it wouldn't work either. Any solutions?
Thanks!

Check and see what firmware version you are running. They released an update on the 31st of last month that corrected such issues. Ver 1.2.0 is the most recent release. If you need to download it check out the kenwood website and look under the support tab -> car entertainment for Firmware updates.

I think we're looking for Google Play store - so we can install apps - but we're locked out. I asked Kenwood tech support if there are plans for more apps and/or the Play store and the guy said not at this time. So any help to break in would be greatly appreciated!

Did the firmware and the bluetooth update and so far no joy. However I'm now having a problem getting text-to-speech working on Ankidroid minus the bluetooth so must fix this problem first.

I wonder what processor runs this unit. If we can find it out by software or opening the unit, it might give us some clues on how we could root it and unleash it's full potential.

Check BT settings on the deck, pandora has to be enabled. Took me a few minutes to figure it out the first time I set it up. It works great though, the BT control is fantastic don't even have to open the app. It just works. I will say after having the deck now for a few weeks, it's extremely nice however my HTC one is a much more powerful machine. You could put a top of line 4G ipad in would be a much more power machine. The resolution on the deck sucks and I don't wanna call it laggy but it's certainly not as fast as my HTC One. Granted a tablet is not made to control audio in a car. I'm sure a lot of the price take is the R&D that went into it, also certain car only functions a phone can't do. Like SiriusXM that you can pause from a satellite feed. Backup camera support which is nice which even works when the deck isn't booted yet. HD radio is absolutely fantastic. I never listed to the radio in the past but all my pre-sets now are HD only. Those thinking about the deck, yes it's cool but it's not the worth the money they are asking for it in my opinion. The built in Garmin Nav is pretty good, like I said a lot of the price tag your paying for the R&D that went into the thing since it's made specifically to work in a car but at the end of the day it's just android.

Look around in the settings, I wanna say I saw some where to shut it off by default. It's actually kinda a neat feature but can be annoying at times. One thing that pisses me off is when scrolling through channel list, it doesn't show what is currently playing. I had an old Sirius radio with boombox attachment that it use to do that years ago. Also changing your preset banks is a hassle if you don't have list view up which I also find annoying. I'm getting use to it though.

RE: Bluetooth
Thanks for the reply. Yes, I think I may have caused the problem when I rooted my Galaxy S 4 and flashed a new rom. I have working now. I have agree with you on the lagging of the head unit. The could have put a little faster processor in the unit, especially for what they cost.

For sure but it's still a great deck hopefully a few more firmware updates will get it even smoother. I have a paid Pandora subscription but there is no way to select bit rate but it sounds decent in the car. I use a rooted htc one with hacked apk and the unlimited skips works perfectly even through the deck which is great. Only bottleneck is sprints net zero 3g network. LTE isn't done yet in my area but it's getting there. Pandora is pretty fast over bt to the deck on LTE.

[Q] galaxy s3 and 2010 Volkswagen audio

Just bought a 2010 gti.. which I'm loving.. I am excited to have a car with Bluetooth..
I got it paired to the Bluetooth system OK, it plays music as tho I had a headphone jack plugged in..
It will play call audio over the speakers and evidently the microphone, where ever it is, is working because people can hear me..
BUT.. I still need to use my phone to make or answer a call.. I've seen in videos people are using the car to browse their contact list and make a call.. I do not appear to have this functionality.. just curious if I could hit the jackpot here with someone who has had this problem
I'm running a custom ICS touchwiz ROM
Tia if anyone has any info on this

Hi! I have a 2012 GTI and just switched 2 days ago from iPhone 4s to GS3. The way I did it I made sure to be in neutral (manual transmission), paired the phone and let it sync address book and everything worked. I suggest you remove the phone from the car and car from phone and try everything again. Im running Blazer ROM[9/23/12][Sup?][LG8][v1.9]
Nice! I knew someone on xda would have one.. do your settings look like this?
The phone audio troubles Me... I feel like it should reference contacts in some way..

In 2010, VW had multiple BT systems. Unfortunately, it sounds like you have the lesser of the 3 (as do I).
I forget the model #'s, but basically there's a top end version that's part of the NAV system which uses the navscreen nicely. Then there is a version used in all the marketing materials that has steering wheel controls and uses the cluster info display for your address book / caller ID. THEN -- there's the real low end, crummy one that just interfaces as an audio cut in with no other integration. This is what I have. You still need your phone for all features except picking up a call (the button on the ceiling can begin / end a call). Lame.
I think your build date determined which BT system is in your car. The good (middle) system was only for very early units. IIRC, there was a class action lawsuit against VW about this - I opted in, still waiting for my check...

That is generally covered by media. For example, my 2009 Ford focus has a similar system (SYNC) which will download contacts into a small address book and save them for me but doesn't reference contacts in the bluetooth settings area.

Based on the reply i got, i definately have the crappy bluetooth.. its just audio output, and it sucks, i still have to use the phone to navigate through music.
the car came with a iOS adaptor.. which does me no good..
i've done some research and have found this: http://www.amazon.com/Newest-interface-Adapter-Volkswagen-Touareg/dp/B004I9CXHW/ref=sr_1_1?ie=UTF8&qid=1370563911&sr=8-1&keywords=vw+micro+usb

i would have a micro USB adaptor that would plug into the propietary mmi port..
our phones don't use USB mass storage however.. has anyone tried this? looking for experiences before i pull the trigger if anyone can help.

Yes the bluetooth sounds horrible
Here's what I did, and it works beautifully..
I picked up the MDI USB adapter, fed a 6ft USB>micro USB through the center console to the dash where I fashioned a phone 'mount' from my Otterbox belt clip.
I noticed it was kind of clunky, and very slow (would take up to a minute for the Premium 8 to even recognize the S3) using the stupid MMS mode. It did work however. I did some research on enabling USB mass storage and found this app: SG USB Mass Storage Enablerhttps://play.google.com/store/apps/details?id=com.mohammadag.samsungusbmassstorageenabler&feature=search_result#?t=W251bGwsMSwyLDEsImNvbS5tb2hhbW1hZGFnLnNhbXN1bmd1c2JtYXNzc3RvcmFnZWVuYWJsZXIiXQ.. It does require root, with Busy Box installed. Now the P8 recognizes the phone in seconds, and is very fast. The app is also nice for syncing content (more on that later). If your phone reboots, you will need to re-enable UMS. I handled that thru Tasker so each time the phone reboots it executes the shortcut that enables UMS. Works seamlessly.. Please note that UMS ONLY works on the S3's external micro sd card. It works great on my S3 but YMMV..
Now as far as syncing content I wanted something as close to iTunes as possible. Part of my mission was to divorce myself from all things "i"- iTunes, iPod, and of course iPhone. But iTunes has always worked well for me in terms of syncing content. Did some more research and found a nice music manager called 'MusicBee'- http://getmusicbee.com/ With UMS enabled it syncs my content very fast.. MMS not so much. On a side note, why they got rid of UMS is beyond me..
Now to handle playlists, and since I primarily use playlists in the car, I use MusicBee to sync those to a standard SD card and plug that into the slot on the P8. Don't use anything larger than 32gig as the P8 only 'sees' 500 folders. There is no limitation when using the MDI port so this limitation doesn't apply the the phone's storage.
One thing I want to mention is that if you want to be able to shuffle across all your folders you need to make sure to put a random MP3 in the root of your devices SD card. Start playing that song first, hit mix and you can shuffle across your entire library.
All browsing is done via the headunit just as you would an iPod. All tag info is displayed on the headunit as well, with the only exception being you can only browse the content of the phone's micro SD- so folder structure is important. The nice thing about this is that you can run other apps (I run Torque) since the MDI is only sees the S3 as a storage device, so hands free calling still works.
It also keeps the phone charged

first of all, thanks a TON for the detailed reply..
based on your advice i went ahead and grabbed http://www.amazon.com/gp/product/B004I9CXHW/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1
and a USB http://www.amazon.com/gp/product/B001QE03GK/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1
i run a rooted rom so grabbed busybox and USB MS enabler.. we'll see how it goes! if not, im out 20 bucks.. whatever haha.. either way its very nice to here from someone with the same set up
Grabbed this too as insurance, at least it will sound better than before
i did also find a 16gb sd i had laying around so i threw that in the car yesterday, but my main device for music is my phone so it would be nice to have everything in one place. Even that is very nice to be able to navigate on the head unit as opposed to scrolling through my phone whilst bluetoothing.
if i may be so bold, are you using something like an OBD2 bluetooth adaptor for that torque app? do you have any recomendations for picking 1 vs the other? would be great to hear from a mk6 owner. there are a ton to choose from http://www.amazon.com/s/ref=nb_sb_ss_i_3_11?url=search-alias%3Delectronics&field-keywords=bluetooth+obd2&sprefix=bluetooth+o%2Celectronics%2C253

Let me know how it goes, and don't hesitate to ask any questions..
I used this bluetooth adapter, and have had no issues.. http://www.amazon.com/Version-Bluetooth-Diagnostic-Interface-Scanner/dp/B008UR7J6I/ref=sr_1_3?s=electronics&ie=UTF8&qid=1370656911&sr=1-3&keywords=bluetooth+obd2

Bluetooth Issues (car and PC)

So, I have been having problems with the Bluetooth on my S4 since I got it, and so have some other people based on my research. I am now hearing scattered reports that whatever update AT&T put out (the apps on the SD card update) has solved the problem. I am wondering how hard it would be to look at the update, see what they did, and implement that change on my device somehow? Or, do you think it's heavily tied into other things that wouldn't make it easy? I really don't care about the apps on the SD card and such, but I really need my Bluetooth to work correctly pairing with my vehicle, and I'm getting annoyed that I have had to jump through the hoops I do currently to make it work when the phone is brand new.
As a side note, Windows 7 is telling me it can't find drivers for my phone as well when pairing to my PC via Bluetooth. This also isn't helpful. Possibly not related to the first problem, but has anyone else solved this? I searched around a little and found not much more than "me too" and "same here", but no one really solved how to get it connected properly.
EDIT: I found some information on this update. It looks like the Bluetooth stuff was definitely patched as I suspected. I am still wondering if we can somehow patch this into our phones.
Reference material:
The updater script is HERE which lists Bluetooth a number of times.
Single posts by user Aou posted HERE and HERE also list the Bluetooth changes.
I also found a copy of the update HERE.
So, can I pull the updated stuff from that file and install it on my phone? Or is it more complicated than that?
I use Ford Sync with mine. I have no problems at all.
You may try clearing cache and data on blue tooth. I heard that can solve your problem.
On your pc insall Kies...it will install drivers fir you. Then get rid of Kies...its useless.
Hope this helps

Thanks for the reply. Are you connecting both calls and media audio to your Ford?
A Google search for "Galaxy S4 Bluetooth issues" will show plenty of people having issues, so it's not just my device. Also, this problem has persisted since new, it has NEVER worked right. It has also persisted through multiple ROMs and plenty of wipes and clears. It is an issue in the device itself, hence why the AT&T update fixed it for other people.
Also, not only are the drivers available separate from Kies on Samsung's website (which I use on my laptop), but I do have Kies installed on this PC and it still doesn't work.
Using both media and phone with hyundai premium audio. Syncs contacts and works perfectly every time. Not a single problem with this phone.
I'm not trying to argue that there is something wrong, but there is obviously something different between various manufacturers of vehicles. Here are some threads discussing the problem:
http://forums.androidcentral.com/samsung-galaxy-s4/278206-galaxy-s4-bluetooth.html

http://forums.androidcentral.com/samsung-galaxy-s4/290639-bluetooth-will-not-auto-connect-car.html
In one of the threads I have read (can't remember which one), at least two people who previously had the problem said the OTA update from AT&T fixed it. That's all I am getting at. I am wondering what it was in the OTA update that fixed it since obviously I am one of the unlucky people who are experiencing this problem.
Maybe I missed it but what's the issue exactly?
Something that's bugging me, and might be your issue also, is when I'm in the car the phone doesn't automatically connect to my car.
I have a 2012 Jeep Liberty equipped with uConnect and everytime I turn my phone on I have to manually select uConnect in the Bluetooth devices list to pair my device. I don't have to reset it up and pair it from scratch but it doesn't automatically pair for some reason.

Yes. Everything works. I just had to delete my S3 from Sync.
I have not had any problems at all.
As far as ur pc goes....dumb question. ..did you restart after installing drivers? Some people forget to do that. Just asking.

This is similar to mine, but not the same. I guess I wasn't very specific, but then again, I'm not trying to solve the problem any other way than seeing the feasibility of porting whatever fix was in the OTA update because I don't believe anything else will fix it. I also contacted the engineering department of the vehicle device and they told me it's a known issue isolated to the Galaxy S4.
Anyway, my phone will reconnect to call audio, but gets stuck connection to media audio and will never connect unless I toggle Bluetooth off then on again. Or, it will connect to call audio, but not re-select the media audio. Everytime I turn off Bluetooth or the car, I have to either re-pair, or toggle it to get it to fully connect. Once it does connect, it's fine.
For what it's worth, the Bluetooth Auto Connect app in the market might fix your issue of automatically re-connecting. Check it out HERE. I had played with this app hoping it would solve my issue by telling it to automatically connect both calling and media audio, but it didn't. Nor did A2DP volume which does similar things. This one can also automatically start an application on connection (for instance I was having it auto start Pandora for me). It also has a feature that can capture your GPS location at the time of disconnect. This means you could get out of your car in a huge parking lot, it captures the GPS location, and you can navigate back to the car later easily. That one can be seen HERE.
Check them out, might fix your problem.

Yes. Multiple times. Again, Google search "Galaxy S4 Windows 7 drivers" will give you a whole list of people who have the same problem...
Strange thing to note. The phone pairs with my laptop running Windows 7 much better. I can play audio through the laptop from the phone, transfer files, etc. The desktop PC displays a message that says the device "needs troubleshooting". When I do that, it says the driver cannon be found, yet it works ok with my laptop. Very strange.
I think I got a fix for you here.

This I can recommend a fix for. I had the same issue with my Clarion aftermarket deck (issue did not occur on my previous Android devices). Google Play Store has an APK called "Bluetooth Auto Connect". This runs as a background process and will fix the issue for you.

Still wondering about extracting whatever they did to the Bluetooth...
Thanks everyone about the recommendation for Bluetooth Auto Connect. Hasn't failed since I installed it, way more convenient now.
Thank you!

Solved: Joying - Mirrorlink Stopped Working After Flash

Hey guys, I have searched high and low for a solution to this problem but have come up empty so far. I just got a joying head unit and everything, including the easy connected app, seemed to work without issue. I decided well since I had the headunit running next to my pc that I would flash Malaysk's custom rom before installing it. After that, I reinstalled the app from various sources including the oem app but none of them seem to allow me to connect my same exact devices anymore.
Why is this important for me? I had planned on controlling a tablet in the back seat for my son who is still to young to put on show without trouble. Essentially, this would allow me to never have to reach back there to help him out.
I have read, from joying, that it would no longer work after flashing new firmware but that seemed to not be the case from some things I had read here (please correct me if I am wrong on that). Tried different cables and ports but no luck. I did read that a license might need to be carried over but not sure what that entails as I can find ZERO info on this easy connected app/problem. I hope that this is a very simple fix and that I did not jump the gun again for the chance to flash a new device (its addicting and I blame XDA for my problems...).
I did try and find some other apps that might allow me to do the same thing. RemoDroid seemed promising but didn't function. Most other ones are meant for controlling from a pc or browser and just weren't useful for the task at hand. I am open to solid suggestions. I use all Android devices and avoid the Apple juice. Any insight you guys can offer will help a tired Dad out. Thanks!
Edit: Solved-ish
The easy connect app seems to function now intermittently. Not sure there was a specific thing that I did to fix it. Seems to work when I launch easy connect app right after booting up and nothing else. Messing with other apps seems to cause a problem for my devices. Also, switching between my devices(phone and tablet) may also have been causing a problem, not sure yet. I suppose I'll just keep trying to make it work reliably until I break it again.
On the previous version of the easy connect app, you were able to disable Drive Mode from launching. Not so on the newer version with Android WiFi. If anyone has a solution to that I would appreciate it as the Drive Mode app is useless for my needs.
Note 4 - USB - works great. I have yet to try over wifi
Note 10.1 N8013(lollipop rom) - USB/Wifi - works great (disable smooth mode, remote device screen cannot be turned on with easy connect "Home" button)
http://forum.xda-developers.com/and...1024x600-rk3188-joying-try-uploading-t3262030
I tried several different apk's but they all have similar results and end with a connection failure.
I haven't yet tried going back to stock firmware so that might be worth trying. I installed the headunit in my car so I'm not as willing to keep flashin it as I have to park down the street from my house.
So not sure what magic I used but I was able to get it working for a moment and then it stopped again. USB and Wifi android mirroring were working so I know my current firmware/setup is functional!! Once I got it working I started configuring some other apps and when I went to run it again it wasn't connecting. I guess I'll just keep messing with it until I can figure out what got it working again.
With the newer version of the easy connected app, I can no longer disable launching of drive mode on connect. Is there a way to disable that option with the 1.4 version?
Hi.
Is it possible mirror in wifi with android?
Can you explain the way?

Any info for this unit? RK-A701

Newbie here, looking for buying my first MTCD. I've found this unit in many stores and eBay, but the only information I can find is that it's model is RK-A701. No MCU, no nothing. At $123,00 with free shipping looks like a good deal. What's your opinion. Has anyone bought one of these?
These are the more relevant specifications I've found:
Android 4.4
Resolution: 1024*600
Max External Memory: 16G
Cores:Quad Core
Display Size: 7"
Memory: 1GB DDR3
Storage: 16G iNAND
CPU Chip: RK3188, 1.6GHz
Doesn't seem to have WiFi
Found here, for example:
Newfrog
eBay (this is the cheapest)
Thanks in advance!
i have this ...
I have this unit, there is wifi, bluetooth is limited to the phone, for the price I find good
If it is Android 4.4 it is NOT MTCD...its and older MTCB device, also looks like it is 800x480 low res screen.
screen is 1024 x 600 , go youtube and search RK A701 ,have posted two video , sorry for my poor english ,am french ..
Better price here:
http://www.ebay.com/itm/Android-4-4...ash=item46520ebb20:g:L6cAAOSwU-pXtWls&vxp=mtr
Just bought from this seller, and even if it do not have proper wifi, i do not see any reason why you should not be able to use tethering either thru usb or bluetooth.
Do this also as many other chinese manufacturers come pre-rooted?
Haha so next up is to demolish the dash in my old astra to make it dual din
This device is not pre-rooted and various parameters are not present, it lacks developper option (solved with a developer apk). Factory setting is protected by pass word (66668888). No button to activate the bluetooth paired for other attachments. Rooting can be obtained with kingroot latest version but after rooting, some apk no longer work .It managed by Luyuan apk.
I have not tested tethering .

Which apps will not load when rooted? do you know was reading about that the radio app was launched thru their weird "launcher" cant be that hard to make it into a service because i really like
apex launcher. Btw did the unit come with youtube?
See this video for response .... https://youtu.be/65J4rU1NPOg
Hi
Do you now be any chance how to put this unit in recovery mode using reset button or others buttons on the radio
Did you check the easy connected app by me It don't work
HI,
I have not found yet and I have not managed to connect it to a PC. Is made by Luyuan and must function as wd8801 .Can be that someone has more info on the wd8801 model ... have one inew u3 phone and mirror link is fully functionnal , on the phone you must turn on the USB debugging .
I also just purchased this and installed it (via ebay)
Boot time is right at 30 seconds.
Backup cam works even before it boots so it works as needed.
Pandora works
Wifi connects to my phone hotspot for data
Radio works
I was able to remove that glowing circle (setting)
Changed boot image to my car logo in password protected area
Allow music in reverse
Installed google maps and changed settings for the GPS button to load goggle maps by default
Phone can make and receive calls via bluetooth
Can't get to work:
Android screen mirroring
bluetooth data sharing
bluetooth for torque app
I was able to get the obdII adapter to pair, but the app keeps trying to turn on bluetooth when it's already on.
I'm planning to get:
USB front camera
3G dongle
Overall very good value. Missing some features of more expensive units, but for the money ($103.49 after $20 off ebay coupon) this can't be beat! Shipped via FedEx so arrived in about a week.
Thanks for the videos you posted.
If anyone can get more use from bluetooth than just the phone, please share. I've looked through hidden menus and tried a bunch of apps with no success.
How did you manage to pair OBD. me only the phone connects, Are you sure it was the OBD who was paired? and not your phone?
Mirror link is functional but you have to activate the option for develeppeur and usb debugging.
look this video for mirror link https://www.youtube.com/watch?v=BLN_yXqqAjM
To get OBD to pair:
Download shortcut manager lite
hXXps://play.google.com/store/apps/details?id=org.vndnguyen.shortcutmaster.lite
Then click 3 dots on right
Search for "bluetooth"
The first link there should be to pair. Click on it, and then click the run (rocket ship). It pairs, but that's it. I can't get Torque or any other bluetooth to "turn on" other than the phone call app and BT audio.
Did you use a USB front camera or another type? I haven't purchased that yet or a 3G dongle.
For dvr cam I have that http://www.ebay.fr/itm/262141040813?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT could be better but enough for me , for forward looking I have that http://eu.banggood.com/Wholesale-Wa...a-HD-Night-Vision-CCD-Camera-wp-Eu-90974.html but I find it very wrong and inverted image , I will change .
Thanks for the links. I was thinking it needed to be a USB camera.
I was able to get mirroring to work on the second try. Not sure why it didn't work the first time.
What was the "free gift" that came in the second package? Mine is expected on Saturday. I'm assuming it's an SD card with map software, but that is just a random guess. If so, what maps? Software? Up to date?
If anyone had a bluetooth USB dongle, could you try putting that in the front USB and see if you can connect that to an OBD or data connection from your phone?
I can't put my hands on one right now.
Mine is came with nothing , gps software installed is igo primo but without maps or sd card , had tested 4 bluetooth dongles , but whitout sofwares for control these dongles , give nothing .
My free gift that I mentioned was junk. Went straight to the trashcan.
Thanks for posting bt adapter results, now I won't bother to find mine.
I tried to root with king root, but after I stated the app, it said there was no root available for the device.
Where I got the app: http://forum.xda-developers.com/android/apps-games/one-click-root-tool-android-2-x-5-0-t3107461
Rooted with Kingroot 4.9.5-149 . Version 4.9.6 did not work with me either ..
Kingoroot was the only app I found that would root it for me. Tried a couple of versions of kingroot and towelroot with no success.
What sat nav apps have people managed to install? I've got igo working after downloading some maps but many of the popular ones say they are not supported on the play store. I tried market helper to see if I could change the device model for the play store but it throws up a token not found error.

Android Auto LGV30 Discussion

This thread is to discuss any and all things related to running Android Auto on the LG V30.
Report problems, discuss work-arounds, recommended apps, etc.
fyi, I am running my LGV30 on crankshaft OS using open auto on a raspberry pi. Open Auto is a Android Auto emulator, and I can report that it works as advertised... great DIY approach to adding android auto to a radio without android auto capabilities.
I have a question... anyone running AA on a V30 has gotten waze to work? For me, I get a blank screen when I try to launch waze in AA, and the whole thing locks up until I disconnect my phone. Google Maps works just fine.

I used Waze with no issues for a trip over the weekend... it was the first time the kids had seen Android Auto in action and it kinda blew their minds - lol.
I just tried to install Android auto on my LG V30+ and get the message that my phone is not supported. On play.store website that is. On the phone, I can't even see the app...I am in an "unsupported country at the moment, however my account, card, phone number etc are from a supported country (UK)
My mobile is even active with the UK number in roaming. How do I make it work please?

I've noticed an annoying issue with AA and potentially unique to the V30. If I make/answer a call in AA then hang up and try to play audio, it plays the audio through the phone speakers instead of via bluetooth to the car speakers. So far have had this happen twice after a call. Unplugged USB then plugged back in fixed it.
If you want to play with some root stuff and want to watch videos on your head unit, there is CarStream for Android Auto. Obviously, it's not good to use while driving but if you eat in your car or just waiting to pick someone up or something, it's a good time killer. It's made mostly for YouTube but stuff like Plex works too.

Wife purchased a 2019 Outback LTD and she could connect her Pixel 2 to the headunit and run AA, but I could not accomplish same with my V30.
This post of yours, and the information on the APKMIRROR site were so helpful. I am up and running now.
Do you know if these variants will be brought together into a new PlayStore version?
Thank you.
Unfortunately I have no idea what google is planning hopefully, yes.
Hello Guys i have a situation with My Android Auto and My LG V30.
I am running an Android radio and installed HUR. Before i Saw this thread i was convinced that the only way to use Android auto on My phone was thru wireless mode which Is good but sometimes i don't know why it suddenly disconnects and i have to connect again manually.
So i Saw this post and it works the "Charging Only" mode i was so happy !! But then i select "charging only" always when i connect the usb and i have no connection so i have to put it again in MTP and now everytime i Want to connect to Android auto i have to go to developer options before i connect the usb and select charging only then go back and connect the usb to the radio and thats the way it works.
Anyone has a similar problem? The radio Is not the problem and neither the usb cable because My wife Huawei P30 Lite works perfect with Android Auto.
USB is a mess on the V30. Connection is extremely unstable with both of my cars. It is not caused by the cable or USB port. Both have been replaced.
