[Q] Car stereo with USB and bluetooth for Android tablet navigation - Galaxy Tab 3 Q&A, Help & Troubleshooting

There are so many options that I don't know where to begin.
In fact, I'm rather lost as I can't really tell if a combination of tablet + car stereo will work for what I want to achieve.
Here's what I want to do:
I am using a Samsung Galaxy Tab 3 8" as a satnav with Sygic.
I currently have an old Pioneer car stereo which works perfectly fine for mp3 CDs and radio but I want to change it to a new unit that would accept a small USB drive as storage for my mp3's. I don't care if it will accept CD's or not (even better if it doesn't).
What I want is this new unit to allow me to play music or radio as normal and, when instructions come from the Sygic App (turn left, turn right etc) during navigation, to get the music interrupted and the instructions heard from the car's speakers. After the instructions are over, the music then start back automatically.
The only thing I managed to sort out is that, for this whole thing to work, both devices (tablet and car stereo) must support the A2DP protocol. The Samsung Galaxy Tab 3 8" does indeed support A2DP for Bluetooth (according to specs) but I'm lost as far as car stereos are concerned.
Instead of looking the specs of every single car stereo available on the market today, I thought I would try asking here first.
Does anyone have anything similar working?
Thanks in advance

Car Stereo with Bluetooth

Hi,
I was just wondering if anyone has a car stereo with bluetooth capabilities. I have been looking at getting one myself. For the longest time I used a treo 650 and had an FM transmitter hooked up to the audio port so I could hear my music and GPS programs over the stereo. Since the Touch only has the mini USB out and I have yet to find a fm transmitter that uses this interface I've basically been stuck using the rear speaker on the phone.
I have seen a bunch of car stereos that are bluetooth capable. I realize that they have to be able to play streaming music via bluetooth and not just handsfree to get the full "stereo effect". My question.... Has anyone tried this out or knows anyone that has used it. Also, how would hands free actually work via the stereo?
Thanks!
Aaron
hmmm..why not just get a bluetooth receiver with a 3.5mm jack. I'm currently using the itech bluetooth clip radio and am able to output stereo music from my touch to my speakers. It also doubles as my handsfree when i'm out and about.
As you mentioned you're using an FM transmitter hooked up to the audio port of your car speakers, this would be something very similar to your existing setup and probably a lot cheaper than getting those bluetooth speakers you mentioned
I needed to replace my car stereo as it is because the display didnt work. Just figured I would upgrade and get one that had bluetooth capabilities but it would seem either no one has tried to play music through a deck with bluetooth capalities here OR that not one has read the thread. Either way I think I'll at least spend the cash and see what happens. Wost comes to worse I just bring it back
Also.. I was going for the whole LESS wires thing.. Having a bluetooth reciever with a 3.5 mm jack that goes to an fm transmitter just.. yeah thats alot of clutter. I'd like to have it where the touch is mounter to the dash (as it is now) and all I need to do is push a button on the car stereo deck and the sound is routed though there. Having the phone plugged in is one thing but then having an fm transmitter and a bluetooth reciever and what not all over the dash is just a pain in the ass I think.
im using the sony/Erikson mbr-100 bluetooth stereo receiver with 3.5 jack. works great.

Is there anything specific I should be looking for. Just.. basically that it can played streemed music and not just hands free correct? That way ALL of the audio will play through the stereo.. not just the phone calls

The magic phrase you're looking for is A2DP. That's the Bluetooth protocol for streaming music from one device to another.
I got a Parrot MK6100 for Christmas, which is a dedicated hands-free kit that plugs into the back of the OEM head unit in my '99 Audi. The MK6100 is both a hands-free for the phone and a streaming music player for the phone too. It's excellent so your proposed solution might be perfect for you if your new head unit delivers the same functionality as this Parrot.
ALL the audio from my Touch is delivered through the car's speakers, including screen taps, TomTom directions, music and so on. There are some caveats though, caused by the Touch rather than the Parrot, I think:
Although the phone functionality works perfectly (it's actually very impressive - I just get in the car and it works straight away) playing music is more complex. I have to reconnect the phone's A2DP output to the car kit before I start the HTC Audio Manager, and I have to exit the Audio Manager before shutting down the car kit, otherwise it crashes and requires a soft reset for the Touch before it'll work again. I think WMP is more reliable but it doesn't integrate into the HTC Cube or HTC Home utilities so it's not a desirable solution for me.
I recommend you test the bluetooth streaming functionality with your Touch and the head unit before you buy the head unit if you can - you might find an incompatibility.

Sorry just saw this post was updated..anyway the clip radio does have A2DP and AVRCP support. Also, there is no need to use the FM transmitter. I mentioned similar..not use existing
but yes there will be a wire going from your speakers into the 3.5mm jack of the bluetooth receiver. If you want it completely wireless, then you will need speakers that have a built in bluetooth receiver..not sure where you can get one though..

I also have a question about htc touch and my head unit Alpine IDA X001.
I'm thinking to buy the Alpine bluetooth adaptater KCE-300BT which works with the head unit i have.
With this adaptater the head unit can display your last calls and let your browse in the phonebook.
Do you think that it will work with the HTC Touch (Windows Mobile 6) I have ??
Thanks
Here are the specs of the BT adaptater of Alpine :
SECTION BLUETOOTH
Version Bluetooth Bluetooth 1,1 CERTIFIÉE
Puissance de sortie +4 dBm Max. (Power class 2)
Profil HFP (Profil mains libres)
HSP (Profil casque téléphonique)
A2DP (Profil de distribution audio avancée)
AVRCP (Profil de télécommande audio/vidéo)
I have the SONY MEX BT2500 CD MP3 CAR STEREO that I had for Christmas and fitted myself. I am really impressed with this unit and it works really well, it also works as a bluetooth hands free.

Hello there,
I have Blaupunkt Hamburg MP68 and the bluetooth on it is excelent. Both handsfree & streaming working fine.
I have bought a Blaupunkt Hamburg MP68 stereo. I am very satisfied by this unit, it is a very complex device and it provides even a built-in bluetooth car-kit.
However there is an issue that I cannot work out: I can't get the stereo to download the phonebook from my HTC HD2 phone.
Both stereo and phone support the PBAP profile (phone book access), but the I always get the message "DOWNLOAD FAILED" on the stereo.
I have noticed that the "Dev A" profile (serial port) from phone's Bluetooth menu has a configuration option named "Local COM port", which was automatically set to COM2. Among the options, there is one called "ActiveSync" (as seen in the attached screenshot). I think that this might be the solution. Can anyone confirm my theory? I can't get to the car sooner than 4 hours from now.....
May be worth posting this in the HD2 forums as well. it has a much newer os with newer features then the touch does, by some 3 years. I do realise that this thread may be related, but people in the HD2 section may be more aware with any bluetooth features specific to the phone as well.
No need to do it, but thanks for the tip. 10 minutes ago I have tested the "ActiveSync" port setting and it works fine: all phone contacts are downloaded into the car stereo.
Cheers!
Grats for doing it then

[Q] Music over Bluetooth to car stereo?

Is it possible to play my HTC One X music over bluetooth to my car stereo?
I have seen evidence in other HTC forums that it might be but I cant seem to make it work, when I pair my phone with my stereo i can make calls through it but when I play music it comes out of the phones speaker instead - any ideas?
If not i'l just use the audio jack cable aux input like i did with my old HD2...

I find it rather hit and miss with me. It does work, but sometimes I have to reboot the phone before it will connect to media audio. Other times it just connects to phone audio, which is very annoying!
Wonder if its a bug?

Check this out:
http://www.amazon.co.uk/Belkin-F8Z4...HUSE/ref=sr_1_1?ie=UTF8&qid=1334252383&sr=8-1
It's a Bluetooth receiver that plugs into the 3.5mm aux. Simply connect to the One X to the BT Receiver and play your music
EDIT: One thing to bare in mind is that is does require power. You would need to purchase a 12v adapter to plug into the cigarette lighter.
The phone will output to your stereo via bluetooth, set mine up yesterday and it was working fine, not used it enough to see any problems but it definitely works assuming your stereo is compatible.
there is an option in the ics music player to pick what output you want it to play to, menu/select player, and your bt stereo should be listed if its paired correctly.
Should display artist track info on your stereos display and allow you to skip tracks etc, didn't actually try that yesterday but my HD2 could do it so will be a bit miffed if the One X can't.

Sorry, but HD2 has a AVRCP 1.3 but all of HTC Android series has AVRCP 1.0 version... Soo, not artist or track info transmit to device.. It's android related thing, not HTC's fault...
But, Samsung Android phones has AVRCP 1.3 (SGS II, Note..)... It seems, Samsung make different bluetooth stack instead of stock android one...
connected my one x to my car yesterday (normal VW golf audio system) via bluetooth.
calls AND sound both work fine, without any problemes. Like it did with my DHD

jabra bt3030 is another alternative, it connects to phone via bluetooth and then you can plugin a 3.5mm headphone cable to your head unit - only thing is , a2dp sucks compared to simply plugging in the phone, its quieter and the quality isn't as good.

Exactly my thought. The only reason to have BT in such a scenario is to let people in the back seats control the music. In all other cases, if you have to use an extension cord anyway, why not plug it directly in the phone? The only BT "dongle" that makes sense (in that eliminates the need for a cord) is the HTC one that plugs directly in the aux jack socket of the car stereo (IMHO, and excluding sound quality from the equation).
Does anyone know of a way to actually STOP it automatically playing music over bluetooth?
I have a Ford Mondeo and had the same irritant with HTC Desire in that once connected, it will automatically start playing music over bluetooth. All well and good apart from when I want to put a film on for the kids in the back and have the audio over the stereo.
All I want is a way of telling the in built music player to not start!

[Q] Car infotainment device

I would like to build an Android car infotainment device to replace all my gadgets inside the car. One option would be a micro PC with USB touchscreen and a lot of devices connected via USB. The other one would be an Android gadget, either small tablet or TV box.
The biggest question I have is: what Android devices support 5.1 audio? This is a must, though I actually can use only 4 channels. What audio formats are supported for this?
The other question would be TMC - the FM kind, not online.
Are there any embedded platforms out there (except PC and Android) which support multi-channel audio?
Has anyone done this before? I might be reinventing the wheel.
No updates? Either nobody knows about Android 5.1 sound output or they are working under NDAs.
Are you planning on keeping a headunit to control volume, do you want am/fm radio, etc....
without a headunit you will need an amp where you can use the headphone to rca adapter and usually its the amp that would add front and rear to the left/right output of your android device so you would still get the 4 chan output effect. to go for the 5.1 chan you will need another device that actually controls the 5 speakers plus the subwoofer which might be tricky but I'm sure its not impossible.
the setup I was going to go with was a amp that I can mount its power controls (left right front back and volume) (or amp/eq combo) to where I can reach it and build a mount for a 7in (possibly diff size not sure depends on how it will look) and use the heaphone to rca adapter to power the audio and put the usb inside the dash possibly with a little hub if they make it (that way not only is it getting power from it, if it allows, the addition of say a thumb drive with added music/movies. some tablets/phones have fm radios built in as long as something is plugged into the headphone jack (my new phone doesn't seem to have it but thats a feature I will be looking for in a tablet)
4chan amp
eq that would allow 2 chan in and 4 chan out plus sub out (if you have a separate sub amp)
I just want to know if there are any android devices that are able to stream 5.1, I can take it from there. Same question about TMC support.
Some details:
My car is already fitted from the factory with 4 channel preamp and 12 speakers including subwoofer low-pass. It has low-level input for those channels, worst case I would buy a preamp.
FM is pretty much given on most Android devices, probably excluding some tablets, but I won't actually miss it if it's not there.
TMC would be nice since all Androids usually have a GPS sensor and sometimes compass.
Anyway, it was mostly a request for suggestions or even a rant - I'm surprised that something like this doesn't exist yet. With the exception of dedicated units going >$$$-$$$$, an alternative set-up would be a medium-range blueray player coupled with an Android tablet. Music control could be set up with DLNA, bluetooth streaming or mixing player and android audio would be a bit harder but not impossible.
hey friends
this is a nice thought and you are absolutely great.
this is wonderful thread

Great Idea
Hi,
Currently I'm also thinking about installing an android tablet in my car to have music, navigation, movie player, speed camera warning, etc. But the biggest problem is the sound. I want to connect tablet with car audio using jack-jack cable. Everything is fine till the AUX source is selected in car audio device, but when I switch it to Tuner or CD - the sound from tablet is cutted off, so e.g. navigation announcement are not heard.
Any suggestions for this issue?
audio rom
its a shame that there are many many roms but none fur special purposes like this.

Only solution can see is to run the audio from the tablet alone. I.e. use the tablet to provide both radio tuner AND navigation. You will end up using the car system purely as an amplifier.

This would be what I would do in this situation. Or just unplug the audio cable from the tablet when using other radio options so the navigation will come through the tablet's speakers.
I want to do something similar but rather than purchase a new device I want to use my Note2. No head unit at all. The Note2 would likely be dedicated to this use and I'd get a different phone to use as, well, a phone.
For sound I was hoping I could use USB OTG to connect a USB sound card with 5.1 output but I'm not sure if this would work. I want to use the sound card instead of audio direct out of the headphone jack because that reduces my connected cables to just one (easier) and should provide at least 4 channel output which eliminates the need for another device to control volume, fader, and balance.
For radio I was going to use SDR for AM/FM (and more) via a cheap USB TV tuner.
http://sdrtouch.com/
Where I'm stuck now is that I'd like to be able to connect an iProduct (iPhone/iPod) like you can to most car radios and control/stream music from the iProduct, via the Android Note2 using USB OTG again. I cannot find how to do this but the Parrot Asteroid Smart runs Android and it seems to be able to do it so it must be possible.
http://www.parrot.com/usa/products/asteroid-range/parrot-asteroid-smart/
Any info anyone can provide regarding the sound card and iPod integration would be highly appreciated.
You can go wireless and use some AirPlay receiver for Android.
I don't know about wired solutions, the classic iPod connector has ~30 pins and some of them are used for audio and some of them are used for serial-like playlist control plus current track information.

It's just a USB to iPod cable that they use for everything else... Parrot Asteroid Smart that I linked to has it as do most modern stock head units.
Did a little more googling and it seems several companies sell android head units that support iPod.
Why don't you use a USB DAC? There are a few out there that are surround sound capable.
Out from the DAC into an eq preamp and out to your existing amplifier. The eq preamp has main volume controls as well as sub control with dedicated output.
Also there are head units out there that are just "receivers" capable of accepting a digital inputs and outputting 5.1 signal via RCA.
I installed a nexus 7 2013 in my VW, currently using Bluetooth to connect to a receiver where it the outputs to an rca input on my deck that was relocated to my glovebox. I am planning on replacing the Bluetooth adaptor with a USB DAC in order to achieve a higher quality sound.
I am currently doing a similar install in a 2010 charger, a deck will not be used however as I will be using the DAC method with an eq and output to the factory amp. I considered going the android TV box route as I have a MINIX box, but there is some work involved in getting the touchscreen to function properly as it is not set up for this out of the box.
You can purchase a double din deck from eBay (I stumbled across it a few days ago but didn't write the link down) it has a dual os system. It uses android for the car audio function and windows for the car PC function. Not sure how well it works but it got reasonable reviews.
Edit: ...and once again I answer without reading the whole thread...:silly:
Is it somehow easier to get all the various apps on the phone to output audio to a DAC than a USB sound card?

I believe when the device detects a DAC (must use an otg cable BTW) it automatically re routes all audio out the USB. You can disable automatic USB audio routing in developer settings.

That sounds easier. Thanks for the tip.
Well I can't find any information regarding the iPod integration and I've found next to nothing for DVD video and audio CD playback and radio and backup camera functionality would also take some mucking about so it looks like I'd probably be better off buying something like this:
http://www.ebay.com/itm/7-Android-4...621?pt=LH_DefaultDomain_0&hash=item2a31320af5
Which has it all sorted out already. So much for that fun idea. No idea what apps they use for all that stuff.

That unit looks slow at only dual-core. It will probably be sluggish when multi-tasking.
The main chip probably supports several I2S devices (aux in/adc, tuner/adc, DVD) and routing plus demuxing is done via linux hardware control.
The DVD player and tuner probably support the i2c or spi protocol to control seeking and other functions. This is again controllable via the linux devices.
Usually the consumer devices don't have these easily exposed and it's probably a non-trivial task to piggyback on existing hardware, assuming the needed connections are broken out on the board. As far as I can see the only Android devices with CD or DVD are the car players like above.
Another option would be to take the sound from the HDMI signal. A DVD player/tuner can be wired in parallel with an HDMI switcher. However controlling the tracks would not be easy, it would require emulating the remote with an IR transmitter.

Galaxy Nexus and Car Head Unit Compatability

I couldn't find anything similar to this. I thought it might be useful for people to post up how well their GNs work with whatever head unit they have in their car (e.g. Bluetooth for calls, streaming, etc.) to help people make better buying decisions. Unfortunately seems like many manufacturers only test against an iPhone before shipping.
Head Unit: Clarion CX609
Bluetooth Handsfree: Semi working - pairing does not complete 100%. It works for that session but pairing must be redone the next time you start the car.
Bluetooth Streaming: Not attempted.
MTP: Head unit shows "Galaxy Nexus" but can't browse through any folders beyond that to play music.
Head Unit: 2012 Kia Sorento navigation system (Kia seems to use the same navi system in all their current cars)
Bluetooth Handsfree: Works fine
Bluetooth Streaming: Works fine
MTP: Not supported by head unit
Sorry for the bump.
Does anyone know of a handy list of MTP compatible head units that work with our Galaxy Nexus?
I am having a hard time finding suitable radios.
The only one I found so far is this one: Sony CDX-GT56UI
But it only mentions MTP in the marketing brochure. In the actual manual it does not mention it at all.
Does anyone have experience with this unit?
I have a JVC unit with Bluetooth that works wonderfully. The unit can control Pandora with info on the HU screen and can skip tracks in Play Music without info on the screen. Calls work from the unit by showing my Gnex contacts on screen and shows the incoming number or name on screen when receiving a call.
Idk about the USB connection because I got the unit to rid myself of cables, not to use a different one.
Sent from my Galaxy Nexus using xda app-developers app
The Sony S300BTX and 310BTX work amazingly well with the Nexus. Call quality is pretty decent on both ends as it comes with an external mic. Streaming works flawlessly as well. This model uses Sony's Tune Tray design in which you flip down the face and a tray spins out for hooking up your ipod/phone/etc. and stores it inside the unit.

Car Stereos with USB

Does anyone have a car stereo with a USB port? If so can you elaborate on what that is like to use? I am purchasing a new unit and that feature is one I do not truly understand. A few questions I have are listed below, but feel free to add anything else you think might be useful in making this decision.
1: Does the phone charge while connected to a USB port on a stereo?
2: Can you use the file system and player controls through your stereo or do you have to control the music and other audio through the phone itself?
3: Does the audio work from all sources with a USB connection(for example phone calls or turn by turn), or will it only play music player audio?
4: If you do have access to the file system from your stereo, will it display song titles and artist info etc? How cumbersome is it do control this way?

It would be helpful to know what actual head unit you're getting. But I will try to answer most of the questions as best I can since I have a fairly new Pioneer HU.
1. Yes, but it only charges on "USB" mode, not "AC".
2. Yes and no. The Pioneer HU that I have does NOT support MTP mode (which is what Jelly Bean, and I believe ICS) uses. Basically MTP is the protocol for storage on the Galaxy Nexus. If you can find a ROM or Kernel or any way to change the mode to "Mass Storage", then you'll be able to browse the file system.
3. Only music (or whatever else is inside your MP3 file). When you connect to your HU through USB, your phone basically turns into a flash drive. From there you have to navigate to your "Music" folder and tell it what to play. The only way to do calls, navigation and music at the same time is to use Bluetooth or a 3.5mm cable with an inline mic.
4. It displays what is inside your ID3 tag inside the MP3 file. So basically, if you have all the info filled in, then yes, it will display it. As far as how cumbersome it is, it takes some getting used to, but not to bad (on Pioneer, I have no idea on any other brand).
Short answer: Unless your stereo support MTP or you can find a way to force "Mass Storage" (which I'm not familiar with a way how), your stereo will only charge your phone. It sucks, but that's the way it is.
Pioneer has the app radio which will control your phone and also allows you to use Pandora on the actual H/U. That said I have never used it nor do I plan on it as its a dual din and I am just happy using bluetooth.
I have a JVC unit that works great with my nexus running linaro aokp jelly bean. The unit is x50bt. It will not play through USB only charge. However it is Bluetooth enabled so it can play anything including you phone calls through your car stereo. I have it setup so that my phone auto connects and plays Pandora automatically. The head unit displays song title and artist and also allows u to thumb up or down using the remote conyrol. I also have playlists set up in power amp for my MP3s. The built in equalizer in power amp along with the equalizer in the head unit work well together. I have the USB cable in the rear USB port so it is hidden in my CRZ. The tiny Bluetooth adapter is in the front and does not look out of place.

Per your suggestion, I purchased the X50BT. I am not disappointed. As you said, it does not support MTP, however I have a tiny 32gb Flash Drive(about the size of the Bluetooth Dongle) inserted in the front and the audio quality is simply breathtaking. I have my phone set to auto-connect via Bluetooth, which it does seamlessly. It even connects for audio however the BT audio stream sounds terrible when compared to the USB audio from the flash drive. I don't know if that's a limitation of my phone, the technology or the unit but it hardly matters since I can fit all of my music on the USB drive anyway. I just have to use Bluetooth or the 3.5mm jack for Pandora. Thanks for the suggestion, I really love this head unit!

If you're rooted, you have to tweak the Bluetooth sound profile using voodoo or DSP manager for example (which one your kernel allows).
You could add some "gain" amp or reduce the "Mids" and raise the "Bass"..
I have a different sound presets for the:
-Phone speaker (added some mids)
-Headphones (optimized for my Sony headset)
-Blueooth (lots of bass and "Rock" setting, sound is pretty good)
Possible Helpful Info on UMS & MTP

Does anyone have a car stereo with a USB port? If so can you elaborate on what that is like to use? I am purchasing a new unit and that feature is one I do not truly understand. A few questions I have are listed below, but feel free to add anything else you think might be useful in making this decision.

This thread might have some helpful info. (especially if the OP dev actually wrote the code for it).

2. Yes and no. The Pioneer HU that I have does NOT support MTP mode (which is what Jelly Bean, and I believe ICS) uses. Basically MTP is the protocol for storage on the Galaxy Nexus. If you can find a ROM or Kernel or any way to change the mode to "Mass Storage", then you'll be able to browse the file system.
Short answer: Unless your stereo support MTP or you can find a way to force "Mass Storage" (which I'm not familiar with a way how), your stereo will only charge your phone. It sucks, but that's the way it is.

I just wanted to point out that even if you found a way to force USB Mass Storage, it is unlikely that your radio would be able to read the filesystem. Most radios will only read FAT file systems, while the Nexus uses EXT3 (I think, could be 4). So Bluetooth/AUX are really your only options.
Gnex to HU

1: Does the phone charge while connected to a USB port on a stereo?
2: Can you use the file system and player controls through your stereo or do you have to control the music and other audio through the phone itself?
3: Does the audio work from all sources with a USB connection(for example phone calls or turn by turn), or will it only play music player audio?
4: If you do have access to the file system from your stereo, will it display song titles and artist info etc? How cumbersome is it do control this way?

I just installed an Alpine HU, It is also does not support MTP. I really like using the Bluetooth but have found that I have to reboot my Gnex and or restart my car to get the Bluetooth to sync correctly. USB does charge but it is slow. One thing to look for is Bluetooth Parrot.

I have found if you just toggle the Bluetooth on and off on your phone it should sync.

I am finding that it is more of how my HU looks at my blue tooth. Thus restart car. I am wondering if it has something to do with Android BT. My gnex has worked this way with multiple roms and BT enabled HU.

I bought a cheap stereo from Wal-Mart a Dual stereo with Bluetooth, takes a SD card, front and back inputs and satellite compatible. It has the USB plug that charges but like the others, doesn't read the memory on the phone. I stream through Bluetooth all of the time with Spotify. My son's Galaxy SIII can connect too if I turn mine off without changing anything. It was a great investment. It is a convertible and the microphone works great at 70mph with the top down. For $118 I am very happy.

I don't believe the Galaxy Nexus will work with the USB of many head units since the Nexus uses MTP instead of UMS.
Hopefully someone can come up with a UMS for the Nexus.

I think the better way would for HU to be able to connect like they do to Apple products and have MTP support.
HU
I know that JVC / Ken-wood have apps for android. Looked more like a HU controller rather then playing from android. Never tested.
I think I figured why my USB isn't connecting from the AVH 4000 NEX to my galaxy note 3 SM-N900. It's possibly due to the MTP mode. I believe if the was a mass storage mode that will work, kinda like a USB stick. I don't think the firmware in my HU is properly picking up MTP, all it does is charge the phone. You need a kennel that has UMS enable for mass storage however the international note 3 SM-N900 currently does not have such kernels. There is only 3.... To my surprise. Maybe the last time I ever go with international models again. If anyone finds away around this let me know thanks.
My car does not have USB or card reader, but aux line!.
So I decided to go cheap and buy a Vieta FM Car Transmitter and BT Handsfree unit, and I does a decent job.
Perhaps in a future I'll go for a Parrot...
