Bluetooth mass storage spoof/hack for car headunit?

Long story short, I'm trying to add bluetooth to my car radio (Clarion NX409). Here is the options I'm looking at.
1. Buy a 3.5mm bluetooth receiver likeTHIS and hardwire it to charge all the time and hook it up to the RCA inputs on the radio
A. CONS:
1. I won't be able to edit the equalizer on this mode (So stupid they didnt enable you to do this on AUX mode)
2. I'm pretty sure you have to turn this device on when you get in the car. This is a problem since i want to hide the device
3. I might get alternator whine since it is charging while listening to it
2. OR, my car radio supports mass storage USB device. (I can play MP3/WMA files on a flash drive). If there were a way to spoof my car radio into playing a file that is constantly being written while the bluetooth receiver receives signal/audio. For example, plug a bluetooth receiver dongle into the USB port, car radio finds one file and plays it, that file is being written at the same time it recieves signal.
#2 is just a shot in the dark. I feel like its possible, but would have to know how to program such and such and also find a bluetooth dongle that you can store a file on. I am open to suggestions and also if you feel like you can do #2, I would pay you what I would ended up spending on the bluetooth reciever, 40$
Thanks,

[Q] Mount as USB Storage to use by Car Audio System

I have a Honda City 2010 Model and it has a usb connection for Audio play (Mp3) , if I conncet any USB storage it will easily detect and play the songs, but if I connect my phone via USB cable it will not detect it. I was wondering if anyone has a solution for it or if there is any application for this purpose
by the way the Audio system can detect IPOD as it is mentioned in guidebook but I don't have IPOD

I would have thought it would need a type of driver that can only be put on when being made.
Something that tells your stereo what has connected, and what to do with it.
Apple being the most popular choice is what most manufacture goes with. If your stereo has line in. you could get a cable off eBay. (Looks like an earphone jack socket. Same as the top of your note 2.) Or what I use, a FM transmitter. I use a belkin tunecast.

Thanks for your reply, I found a way to mount external microsd card using usb mass storage enabler application, now I can play songs in my phone via car audio system
I remember when I had nokia phone there was one application to use FM to play the songs in phone on car audio system. is there any app for android to do so? or is NoteII capable of doing the same thing?

No there is no such app because it's actually a hardware fm transmitter where as note 2 doesn't hav that

[Q] Car Stereo Unrecognized By S4 When Connecting Via USB

O-for-two...<grumble-grumble> :crying:
Upgraded my factory cassette car stereo to a new one with usb port (no bluetooth), thinking I could both stream the phone's audio and charge the battery via usb.
Well, the battery's levels actually decrease when plugged in, and more to the point, the phone isn't recognized in usb mode in the stereo and quickly goes to radio mode and the phone displays the following message (please see attached screenshot)...
...my phone is stock, not rooted. Stereo is not bluetooth-enabled, and I would prefer to stream via usb than the aux port.
-> Can anyone advise any tweaks or apps that would enable the phone's streaming audio to be played via the stereo's USB mode?
Thanks in advance!

Thanks for the reply.
It's a 4Runner.
Hoping to focus here on how to get the devices to recognize one another...

That's weird. Maybe a driver issue with the stereo? Does it have a hard drive? Never used stereo with usb port. I think my wife's suv has one.

The stereo is very basic, no hd.
Anyone know of any tweaks/downloads I can make to the phone in order to get the audio properly streamed via usb?

I have a similiar radio. No bluetooth but a usb on the front and an audio input on the front. As I understand it the stereo itself can't access the phone this way. It doesn't have drivers to recognize the Samsung phone. Think about it. you plug your phone into your computer by usb but you have to download and install drivers for the two to work together. Mine from the looks of it has Iphone drivers built in but nothing for android. You can probably plug a thumb drive in loaded with music and it'll play. What I do is use a stereo cable from headphone output on the phone to the audio in on the stereo. If I need to charge it I have the standard car charger for that.

Youre doing it wrong
The reason the battery is decreasing is the amount of current drawn from the device. Either the radio is not strong enough to supply the right current or the phone is recognizing it as a computer and limiting the draw to 500ma. My rough estimates show that the phone uses closer to 750ma while in use just to run. You can verify how much power it is drawing with this simple application https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free
You could try to install a kernel that allows you to override the amount of power drawn from the port. I was the first to request the feature and Ktoonsez was nice enough to implement it into his kernel. Now you can set the AC and Computer USB draw to any amount you like.
Secondly, why did you think you could play audio through USB in the first place? I guess it would be possible if the radio supports MTP but then the phone would be acting more like a USB stick and you would have to choose the files manually on the radio itself.
If you really don't want to use an Aux cable then I suggest buying a bluetooth dongle and connecting it to the rear AUX inputs on the radio. They are relatively cheap and you can install it inside the dash never to be seen again.

This is all really helpful info, thanks
Yeah, not sure why I thought I could stream via usb either, must've been mixing up the functions of that and the aux cable.
-> So I'm familiar with a bluetooth dongle that connects via usb (...think that would work properly in a car stereo too?) - but you're recommending a dongle that connects internally? Know where I'd find that for sale?

1st, my assumption is you're rooted...?
If no=Boohoo... Root or buy stereo with Bluetooth.
If yes= install this app... https://play.google.com/store/apps/details?id=com.mohammadag.samsungusbmassstorageenabler
Open it, grant it root privileges, click the "mass usb" (I think its called), and profit!
*Music must be on external card.
<-- my thank you is over there

Do you have an auxillary input option on the stereo? 3.5mm jack...
The advantage is that it's guarenteed to work.
The disadvantage is that you can't control the song selection from the stereo. You have to do it from the phone.
Also, could it be there you store the music? If it's on an external SD card I can see where that would fail. Maybe if it was on the internal memory? Remember the car stereo probably isn't real bright. If it doesn't find what it's looking for where it expects to find it, it won't keep looking.
You might have to have it stored in a specificly named directory on the phone too.

"Internally" meaning it goes inside the dash, behind the radio. Its just a bluetooth receiver with an audio output (either a headphone jack or RCA cables)
If you want listen to music over "USB" you can get certain touch screen radios that will mirror your phones display

There is a mod that allows your phone to emulate a usb storage device that would allow you to play music stored on the phone through the stereo you installed, however there would be no controlling any of the sounds, etc via the phone. All the controlling has to come from the stereo itself. Volume, tone, selection, etc. You also need to check the format that the stereo "expects" to see in order for it to be able to function.... Such as Folder size, (files within the folder - how many) How deep the folders are allowed to be set as like in subfolders, etc. What the storage media format is able to be accessed, etc. It gets a little technical and the results are a bit disappointing in the end...
The best I can recommend is a display screen unit that supports using the phone in the USB input. I just installed a Pioneer AVH-X4600BT that works with my (GS4 rooted 4.2.2 Stock ) in my Wife's Subaru Outback. We can plug the phone's USB cable into the stereo (via a Mirrorlink add-on) and run the PHONE using the touch screen of the stereo. You'd be able to run Pandora, answer/make calls, answer/create e-mail and Texting, listen to the music on the phone, watch video that is stored on the phone or DVD's, and most important, NAVIGATION on a 7 inch screen!. All of that though, is dependent on the phone you have. As of yet, the Mirrorlink supports the iPhone, GS3, GS5, and with a hacked app in the phone, it also supports GS4. There is a free app on the market that is called Drivelink which interfaces your phone and the stereo.
You might want to research other stereo devices that have the Mirrorlink application support. I believe Sony has some, but I didn't go past the Pioneer unit. Bottom line, BE SURE TO DO THOROUGH INVESTIGATION ON WHAT YOU WANT TO DO AND THE CONNECTABILITY OF YOUR DEVICES. I know you just bought the unit recently so you just might be having to live with your setup for a while. That's o.k. though, next time you purchase something like that, you will be armed to the gills with knowledge and get something you'll really enjoy.
On my test bench after testing, and was ready to be installed....
Good Luck, and Aloha!

It's doing that because your phone uses MTP as the Media Transfer Protocol. Basically, it kind of mounts like an MP3 player or camera and the new DIN you installed doesn't know what to do with it. The real trick is to get your phone into UMS, USB Mass Storage mode. There's a UMS app in the play store, BUT you have to be rooted to use it. It basically mounts your phone like a regular old thumb drive. Do that and your new DIN will see it no problem. Only thing is, like a USB drive you'll have to navigate into your folders to play your music. This was what I threw in my car and it's been awesome!

I bet I know why you thought you could play audio through USB. It's because Apple products can do it. One of the things that drives me nuts is that most cars with USB ports have audio playback support for Apple devices because of Apple's dock interface that let's the docking component control and navigate the audio. Unfortunately (and it drives me crazy) Google hasn't created a similar interface for Android so there are no Android Docks. Android devices like the S4 in your car rely on on AUX to send audio. It really sucks and Google has committed to addressing it this year in the car but I don't know if they're fixing the underlying problem of a uniform audio interface in android; meaning one where you plug in a dock and it recognizes your phone and how to access your music and playlists. Again, Take a look at this if you need a quick fix. I know you were hoping your new stereo would do it, but you could easily hide this:

I don't understand, am I missing the post where u said u did this and it didn't work?
This is what u need to do... period. If this app won't work with your rom, find an app or place in the settings to enable "mass storage". The above linked app works for me and many others.

[Q] Car mode

Does G4 has car mode? Is there appropriate cable, car dock?

Also interested in knowing this.

I just got my Sprint G4 and Car Mode is working fine, including "home" going back to the car dock app. I'm using Car Dashboard for the app. I'm also using Bluetooth Car Mode to set the phone to car mode when it connects with my car.
It "just worked" for me... but I also did an LG Backup from my old G2 to the G4, and that transferred all this over to the G4.

There IS a car mode, but as far as I know, not launchable in the conventional sense. I use Tasker to activate car mode when I plug the phone into the car. You can also set it to car mode when connected to your car BT.

What does the car mode look like, or how could I try it out on my phone?

Nothing really - just an icon in the notification bar, and that screen brightness is at max. There's no Google Car Mode app or anything built in.

Can just add: when Car Mode is initiated, the call AutoAnswer becomes active and works without switching on Call auto answering in LG menu

I use Bluetooth Car Mode Starter to start car mode when the phone pairs with my car's bluetooth:
https://play.google.com/store/apps/details?id=com.mohammadag.bluetoothcarmodestarter&hl=en
Prior to that, I used the Car Mode app to enable car mode manually:
https://play.google.com/store/apps/details?id=com.schwimmer.android.carmode&hl=en
(alternately, as mentioned about, you can use Tasker)
The Car Dock Settings app is helpful:
https://play.google.com/store/apps/details?id=net.cwfk.incar&hl=en
I've actually got the old Google Car Dock on my phone; I plucked the APK off my Galaxy Nexus and Google has moved it forward for me every phone I've had since. It's really ugly. As I said, I prefer "Car Dashboard".

I was trying to do exactly this. Do you know what activates car mode? I know I can use NFC but I was hoping to replicate a setup I had on my S4 where I plug into a dock and tasker detects it is in dock mode. If I recall on my Samsung S4 had to modify a USB cable for the S4 to detect this.
Cheers!

Within Tasker I can search for Car Mode, but I have no idea how to find and initiate merely from the phone.

Any ideas on how to activate Car Mode?

I used my M8 in the car a lot but most of what I need involves Car Mode being active on the phone, it was no problem with the M8 as the HTC car kit contained a USB cable that enabled Car Mode when you plugged it in.
HTC assured me that the 10 was compatible with Car Mode and it was the dock part of the Universal Car Kit that activated Car Mode and not the USB cable. Their Universal Car Kit only comes with a Micro USB Cable and not Type-C cable that the 10 needs. Turns out it's most definitely the cable that activates Car Mode and not the action of placing it in the dock, so as there only seems to be normal USB Type-C cables on the market I can't get Car Mode to activate when I use the phone in my car.
Does any one have any ideas? HTC's social teams online are useless, even after telling me that the 10 was definitely supported for Car Mode when it wasn't they just kinda shrugged it off with no real answer.

It isn't installed on the HTC 10. They lied to you.
You will have to install them from this http://forum.xda-developers.com/htc-10/themes/patch-one-patch-missing-sense-apps-t3362787 but you will need to unlock your bootloader, flash TWRP and flash it through recovery.

Alternatively android auto in app mode will be out soon and likely sufficient.

Sorry I should have been more specific, I'm not on about the "HTC Car" app, I'm on about triggering a Car Mode action dock event.
A lot of the apps I use function better when they're triggered by a dock event from Android system rather than being triggered by a Bluetooth or charge event.

Easy. If you want to trigger car mode, just install an app that does just that. My weapon of choice would be Tasker. That way, you could trigger via an event or anything else really (e.g. bluetooth connection, NFC tag, whatever you like).
You could even simulate a dock event.

Thanks, I'm having a look at Trigger, it looks like I can get it to trigger a car dock event when it sees that the phone connect to the car's Bluetooth AND is charging. And then it'll send an undock event when it disconnects from the car's Bluetooth and stops charging.
Will see how it goes when I get in the car later!

You may also like the Drivemode app. I'm using it on HTC 10 and it works pretty well. Triggered via BT connect to your car, but seems to trigger reliably.

I'm not using a HTC10, but found this thread when looking for the same thing as the thread creator here. I also used my HTC One M8 up until about a month ago with the HTC Car dock and the "special" cable that triggered car mode. From what I can see from this thread: https://forums.androidcentral.com/epic-4g-accessories/64959-what-triggers-car-dock-mode.html, it seems like the magic to trigger car mode is that the cable have a 619K resistor between pins 4 and 5 on the micro usb cable.
Does anybody know if something similar is valid for Type C usb cables and in that case where to get those kind of cables?
Since I got my new phone (which unfortunately was missing NFC, so I can't use RFID stickers in my car dock) I've used a Tasker profile to enable bluetooth on "Power AC" (=wall charger or 2.1A car charger) and then another Tasker profile to enable car mode when it gets connected to the car bluetooth, but this means it takes quite some time before my car home app gets started since the phone first has to enable bluetooth and wait to connect before launching the car app as opposed to with the M8 that triggered car mode immediately when the USB cable was being plugged (by docking the phone) and then let the car app enable bluetooth.
