Strange issue with mounting USB to car stereo, but not the PC

I have searched all over and I am not having any luck, so I am hoping that someone here can help.
At the beginning of Oct. I rooted my incredible using unrEVOked and the Stock HTC Rom. Everything was working fine at the beginning until a few days ago when I went to go plug my phone into the USB port on my car stereo, this is where it gets weird. First the stereo was not able to recognize the device, which it was able to before, and it doesn't even attempt to look for anything, almost like I didn't plug in anything at all and the Battery light keeps flashing on and off. Thinking it might be an issue with the stereo, I try it with my wife's DX with the same USB cable and it works fine. So it is not a problem with the stereo or cable. If I leave everything plugged in to the stereo and reboot there is a few seconds that the stereo is reading the phone, but as the phone gets closer to finishing the reboot the stereo stops recognizing the phone.
In my attempt to figure it out, I first did 5 different restore backups neither one worked. I unrooted and did a factory data reset and that doesn't work. In my frustration I rerooted using unrEVOked again and this time I flashed virtious ROM and Kernel, this didn't fix the problem. So I tried a different ROM and Kernel this time using Redemptive rEVOlution 1.8 along with the Hydra Kernel and again no luck.
The strange thing is when I plug my phone into the PC, both internal and sd card drives are seen and I can access the files just fine. It is only when I go to plug it in to the USB port in the car is when it is not finding anything. My car stereo is not picky when it comes to internal or external phone storage and I have put music on both drives and it does not read either one. It is almost like a file or program got erased and nothing I have done is able to fix it.
Anybody have any ideas that might help?

Have you tried copying all the files on your sd to your pc then formating the sd card fat32 from windows and then copying all your files back to the sd. This same thing happened to me once drove me nuts couldn't figure it out then I had to format my card for something else I was doing and after that it started working fine again.
Also this may sound obvious but you do have the default pc connection type set to disk drive right?

Speculating here, but ~
Is USB debugging checked?
Maybe toggle that - Unknown Sources toggle as well.
Settings>Applications>Unknown Sources
Settings>Applications>Development>USB Debugging
Maybe toggle mock locations as well - found in location w/ USB Debugging.

I have the same problem with my Vibrant. I have an Alpine IXA-W404. When I plug in my phone via usb, it shows "searching" then "not supported" but on my head units screen it starts to show some random music files on my phone, but won't play them. I tried plugging in using two different wires, and tried with debugging on and off.
Any help? I even saw a video where the guy was doing it online with a similar setup, using a Droid and some other similar Alpine deck.
Thanks!
-edit-
when i select "media player" from the usb settings on the phone, after about 20 seconds, the head unit starts to play a few songs but its very choppy. Any help is appreciated!

This fixed my problem before when I had issues like the OP is having.

Longshot here, but this happened to me w/ my vehicle when I put a ton of mp3's on a thumb drive, and not a specific folder on the USB....
Is the vehicle trying to index the contents of SD card or other device drive and cannot?
Is the music or other content on the device in a specific folder, or spread out amongst directories/folders?
Have you tried copying say the mp3's (whatever content) onto a flash drive, and whether the car 'sees' them?
Speculation: the vehicle is trying to catalog/index the files/content ~
As such, there are either too many for the vehicle to index, and/or desired content to be read by vehicle need to be consolidated into folder(s) the vehicle can see, read, and index.
Imagine the brain in the vehicle can only index so much content.

still was not able to get it going with all of the above, i downloaded "auto mount sd card" from the market after hearing that it helps but still to no avail.
any more suggestions? this is something i'd really like to use my phone for!

Maybe let us know the device that you're connecting it to.
Oh yeah, also some after-market USB cords will only charge and not send any data- so make sure that isn't your problem either.

Could this have something to do with the usb apk? I've used a lot of different roms and some would work and some would not. I'm currently using a Sense 3.0 , Nils Business 3.0 and it doesn't mount to my car stereo.

I just restored an old backup of a rom Warm-Z and the mount worked, no problem. I then went back to my current sense 3.0 and it doesn't.

Car stereo USB

I could connect all of my other android phones to my car stereo with the usb. But now it isn't working at all for me with the GSII.
Thinking maybe I need to put the music on the internal storage and not the microsd?

That's a great question, but, I think the reality of the situation will be worse than that as it doesn't mount as a disk drive in quite the same way. I'm sure AOSP roms can address this, but, until then I'm not so sure.

when you plun in your ET4G to your stereo you should be able to navigate to the external sd card
on your phone its under
/sdcard/external_sd
i hope this helps.

OP, were you able to fix this issue? I'm having the same problem with my Epic 4g Touch. Unfortunately, my clarion cz300 stereo does not allow me to navigate to any folders. It automatically scans the entire sd card for MP3 and WMA files.

you should PM him and ask him to reply in this thread for us all to see.

Try going into the settings to wireless and network > USB utilities. press the button to connect as a storage device. This works for me. Can't remember if I was able to switch it before or after I connected the USB cord. It's been a while since i've had to use it. Let me know if that works.

Thanks, but I've already tried that to no avail. I've read through 20+ threads and tried every single suggestion. I'm starting to think my phone is not compatible with the stereo.

Using Galaxy S III with Car Receiver

Does anyone know why there would be problems using the Galaxy S III with the Alpine cde-hd137bt with USB connections
I can connect the phone, but it says "still searching"
Does it have something to do with Mass Storage? although I am a novice and don't understand what it means some phones support it, some dont. The Galaxy Nexus, I just plugged and used it. The GS2 and GS3 the menu comes up on the notification area, to select USB, although it is automatically selected you don't have too Weird
But the installer said it may be due to a basic incompatibility, maybe with android, and I have to use a flash drive usb. He said Alpine has become very "Apple oriented."
(as an aside, I did have a hard time connecting bluetooth wise, but only once. I googled and saw a post of someone having problems. I just ask so I know if I will experience my problem again -- is that a known problem)
Thanks to all who read and those who can help also

I think it's because the S3 doesn't do usb mass storage, instead it transfers media through mtp (media transfer protocol). So if your radio doesn't support it, then you're out of luck. the same thing happened to me with my car radio, so I know how bad it sucks.

Thanks a lot. What kind of head unit did u get
I love the Alpine. I had the cda-9856 and loved it but wanted Bluetooth
Also have pheonix gold speakers and had to get new tweeters today, Focal. Sound awesome
Have Pioneer Amp and Xenon crossover, is that sound right. O'Malley
Anyway, no biggie about the USB. Just wanted to make sure it wasn't me. Especially no big deal since I found I can't use Slacker etc thru US B. I will just use BT or Aux. So many options

[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.

i am bumping my crazy old thread with another VW GS3 question if anyone has any info:
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
Here's a few pics of my setup:
Any questions, don't hesitate to ask..

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

[Q] sgs3 USB communication with my car stereo

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:
