I want to connect my Windows mobile to My car's Head unit using a USB and I want to play some music which should run in my mobile and the audio should come out from Head Unit's speaker (via USB) . What are Protocols are available for developing such applications ? And How should I approach this ? Is there any kind of reference available ?
It depends on your device whether the USB supports audio OUT or not.
HTC devices often do, but then it's not a normal mini or micro USB port anymore but a specific one.
In the latter case you simply need an adapter for connecting normal USB and audio OUT at the same time.

simply connect your device using the provided usb cable to your car's player and choose "Device Storage" mode. you can try putting your audio files on the root of the storage card.
you are gonna need an FM transmitter and an auxiliary cable to do this.

he may not need an FM transmitter or an auxiliary cable, since he has this feature (direct usb connection) in his car's player.
Hey Guys,
I need your help. I currently have a carputer running Windows XP in my car now with an 8" touchscreen interface. It works and does what I want it to but I'm thinking I want a cleaner solution. At first, I was thinking about loading Android onto it but then I was thinking I could probably go one step further. My EVO does everything I currently have in the car (nav, music, video, etc) and it'd be awesome to use my EVO as the CPU if I could get it working with a bigger screen. Is there some kind of device on the market that acts as a remote display/screen that allows seamless touchscreen functionality? I'm talking about mirroring the display of the EVO. Like via bluetooth or HDMI out with USB interface for the touchscreen function?? That would work so much better because all I would have to do is mount the screen and run power to it. I could completely remove all of the computer hardware saving space and points of failure. It'd be best via bluetooth that way I wouldn't even have to take it out of my pocket. If there was a way to get it to work with the HDMI port for the video/audio feed and the micro-USB port for the touchscreen interface, I could just run a dock in the car and work it that way. If anybody knows of a device or a solution that would accomplish this, PLEASE let me know! If you think you have an easier/better idea, please feel free to share that as well! Thanks!

I know there are several developers on the brink of completely unlocking the HMDI port functionality so I know it can be accomplished...but getting the touchscreen to be seamless I think would be the most challenging part...
Ok, so after changing some search terms, I was able to find something similar: Mimo USB Monitor. The entire monitor (power, video feed, and touchscreen interface) is though one USB connection. I came across this XDA thread that pretty much explains how it could possibly work: http://forum.xda-developers.com/showthread.php?t=898418 Has anybody done any research on this or know anybody that has or is currently working on something like this??
Any ideas??
That wont work. The usb port does NOT do video out. Your only option for video out is the hdmi port, which as of right now, will only output video and pictures. As said above, there are dev's working on full hdmi output, but who knows when it will be available.

That monitor is a standard USB DisplayLink device. No special video out needs to be on the port, you just need a device capable of operating as a USB host with the correct drivers loaded (which are open source on normal Linux and thus should be portable to Android if someone was so inclined). Thus, any phone which could be used with a USB keyboard, mouse, thumbdrive, etc. can support that monitor.
That said, I've looked a few times and do not believe the Evo has USB-OTG support and it certainly does not have a standard host port, so we may be SOL there. N1 users can do it for sure, I'm pretty sure I've seen it used with an Ubuntu install, creating a kind of hacker's version of the Altrix around a year earlier.
Alternatively, it's not the fasted method, but there are a couple of software solutions that basically let you VNC to your EVO from the PC. androidscreencast is one (google that phrase, can't post links yet) but it seems as though it's stalled out. I think that Droid Commander (or something like that) also has a screen casting option. This way you don't have to worry about touch screen drivers etc.

I wonder how a cheap chinese tablet with a usb host would work.
I've considered just installed a cheapo tablet in my car then go out to rca's or a bluetooth transmitter. My line of thought on is most headunits/music is only stereo(2 channel), so you wouldn't lose anything there. The two big problems I forsee would be a reduction in the the output quality using 3.5 to rca and finding one with a fm radio thats worth a damn.
Well if you really wanted to go a tablet route. there is the smartq v5 you can pickup for around 250. it has full hdmi out usb host bluetooth and hardware video decoding (1080i hdmi video looks soo nice on a tv form it). You can download the android 2.2 firmware and run rocketplayer for allmost any video.
So I'm getting a new car tomorrow (2012 Chevy Cruze) and I know it has a USB port that allows charge/data.
I've been reading around the Cruze forums and it sounds like I can't stream Pandora/Google Play Music via the phone plugged into the USB port, but rather instead, I have to have an AUX cable and go through that. The disadvantage is I have to control the music via the phone, not the in-car console, amongst other things.
Has anyone had any luck getting an Android phone to stream Pandora/GooglePlayMusic through a USB port without using any mods or the AUX port? Apparently it works with iPhones, but not with Android.
Just was curious if that was true. Either way, I'll find out tomorrow.
I have a 2012 civic and my usb port in the car makes my phone go crazy so I haven't plugged in again. I have used bluetooth for pandora and it works. I can control volume through car.
no usb audio
Our phones wont do usb audio on car stereos. For some reason you can not mount your drives, i had a nexus s and evo that would mount though. It has to do with how samsung configured the system. I just went ahead and got a bluetooth system because it is easier to control the sudio from the phone and also hands free calling

Might be something in this that may help you out if you haven't seen it already.
Sent from my SPH-D710 using xda app-developers app
Maybe this line out with usb type thing will be helpful. I haven't tried it yet but I'm going to be cutting apart one of my cables soonish to see if it'll work.
It's basically just using the dock audio setting for the Galaxy SII.
From what I was able to find, this isn't capable with current versions of Android and I found this information on the code.google website. If you do a google search for "android audio out through usb" it should be the second result listed with "Issue 24682" in the title.
However, it looks as though Android is going to add this function starting in Android 4.1 (Jelly Bean). If you do a search with "android audio out through usb jelly bean" you'll get more info on the official details.
Good luck with your new car, hope this information helps.
There are a few aftermarket radios with partial support. The best I've seen is the AppRadio 2, but that's pretty expensive and I don't remember if it gets along with Google Play Music. I'm really interested in finding a good solution as well. My iPod Touch's battery life has gone to crap and I'd love to get rid of an Apple device rather than repair it.
I wonder if apps can control the USB port on Android? If so, one could potentially develop and app to spoof an iDevice...
You should be able to use the car radio volume with auxiliary.

I have Galaxy S3 and I upgraded to Jelly Bean, in hopes it would work - but it didn't.
In the Settings app, under Accessories, Jelly Bean users have a new option to play audio via external devices (they refer to it as "docks" which seems not too broad).
Apparently, this does not work unless the device was setup to support Google's audio protocol: Android Open Accessory Protocol 2.0 (AOA).

Hello,
I just recently bought a Chevy Cruze eco 2012 - i didn't research about my android phone and i was dissapointed the bluetooth doesn't work as A2DP. I should of waited for a Eco 2013 includes mylink
I has to research later and found out that it's not supported. what i'm using now is a usb sitck to play my music and sometimes AUX.
I also read that we can use the bluetooth blackberry stereo gateway nad stream our music - i'm thinking of purchasing one.
Ahhh!!!
Also there is a hardware hack lol you can replace the bluetooth module PDIM from a Camaro.

http://www.cobaltss.net/forums/electronics-audio-video-49/updated-bluetooth-module-281218/
I have been thinking about the PDIM not convinced 100% i dont wanna mess it up lol
I also try using the USB switcher mode to change to usb storage but i get an error for music data not supported.
If you find anything let me know
I've searched around to different forums and haven't really gotten a clear answer for this. I used to be able to play my music from my iphone simply by connecting it to my usb plug in my car. the sgs3 doesn't do that. I've read it is because it uses mtp instead of ums for data transfer now because there are no partitions in the drive. Supposedly there is a way to use ums by an app that was created for the i9300, but I have the US sprint model and I wonder if that would work on my phone. Plus I would like to know if I use this app, will it even solve my problem? Will I be able to listen to my tunes in my car without connecting the audio aux plug?
Thanks in advance,

I would like to know this too, My car radio doesn't have bluetooth support, so it's not an option for me and it doesn't work when I plug the phone in. This is the only thing keeping me from getting rid of my iPod!
I'm curious about this too. I just bought a Sony for its Sirius capabilities and it has Pandora support but I would like to listen to my phone's MP3 catalog too.
sent through the third galaxy
I just replaced my car stereo thinking I could use the USB in, I couldn't get it to work by default.
I'm left with using the aux in, which is nothing more than a stop gap solution.
Hoping that I can get it to work with usb too
Edit :
I forgot to try system >accessories >usb audio
I'll try when I get out of work.
2nd edit :
Didn't work
Sort of the same issue, compounded.
I have a 2012 volt and an S3/I9300 international version. I can't get it to play audio in my car for love or money. No roms, just stock...but bluetooth and auxiliary fails. Bluetooth says it doesn't recognize it, auxiliary jack says everything is hooked up but I get no sound.
I also have a bluetooth soundbar in my home; the phone connects fine but the sound comes through the phone still rather than the speakers. I feel like I'm missing something pretty basic here. Any help/guidance would be much appreciated. If there is an app that will fix this I'm totally game. Also anything to get rid of the samsun apps login that is constantly annoying me, or the German news sides that are preinstalled.
I'm a wreck lol. Love the phone otherwise though (other than ATT delivering my text messages roughly 72 hours after they were sent...all at once, from 3 to 6 am, like clockwork. I switched to t-mobile).
Wrong section dude, you want the international forums, this one is for the sprint variant only
I would suggest searching for usb input on the stereo and making sure its selected as the playback device. My ford fusion has bluetooth and usb but when i use usb i have to select it on the stereo to actually play music from my phone. Hope this helps...:good:
Hey guys,
I just bought a Pioneer stereo system that supports Android MTP and it claims that it can read Android devices with version 4.0 and higher that use MTP.
But for the life of it, I cannot seem to get it to detect my m8.
I'm not sure if it's the phone? or the player... i've got a hunch its the phone... but who knows..
I've tried using drive droid to set the usb settings but nothing has worked so far...
This is the model of stereo I've bought: http://www.pioneer.com.au/au/products/DEH-X2650UI/print.html
I know i can just use the AUX cable but i just wanna try this MTP thing out...
any help would be greatly appreciated!
Support for various devices (like car stereos) for things like Bluetooth and USB has always been a bit iffy. It would not be surprising to see MTP support to similarly have patchy compatibility.
Unfortunately, such issues can also be difficult to resolve, or even troubleshoot.
