[Q] Play music from SD Card through USB - Atrix 4G Q&A, Help & Troubleshooting

I have watched the noob video and looked through every similar post I could find with no success so here is my situation.
I have been an android user for all of a week. I gave my iphone 4 up for an atrix because I wanted the freedom. I have it rooted and unlocked thanks to you wonderful people on XDA and now I'm running the cm7 beta.
I have a pioneer 3200bt in my car and I have always plugged my iphone into the usb port and played music that way. I can't get it to work with my atrix. I have tried no external sd card, external sd card, mounting it for memory card use, usb debugging mode, no usb debugging, un/checking the "use internal memory" in cm7. With every try I get the same "Unplayable File" on my head unit. I thought it would just mount the sd card as mass storage and I would be on my way but its not that easy.
If I take the sd card out an plug it into my stereo it works fine I can play all the music on it. Using that way is fine but my phone won't be charging. The headphone jack would work too but analog sounds blah. I'm prepared to blame it on my head unit if I have to.
Does anyone have any ideas? Apps, mods, hardware? I greatly appreciate your thoughts and responses.

Besides the obvius answer of saving a little battery, why not get rid of the cords and use the bluetooth? The audio qaulity on my Pioneer xxxbt sounded great over bt (I clunkered my old car and bought a new one that I dont want a custom deck in). And I had two 12s, the quality was >= a 3.5mm.

Thanks for the response. I'd like to be able to do that too. I didn't realize the 3200bt was ghetto and only supported phone calls over bluetooth and not that A2DP.

Watch out if you are planning on streaming music or pod casts while using Bluetooth for audio. I was just served a notice about my Illegal tethering from ATT. I do not use tethering but they told me if I am streaming music through a Bluetooth device, it is considered tethering and they will add the plan automatically. I had been on the phone with them for over an hour about this and they have concluded that streaming anything ( music, pod cast or video) using your phones built in Bluetooth is considered tethering. I too have been listening to my music through my car stereo via Bluetooth and have recently received the notice because of my use of Pandora while doing so. Just trying to help.
I would love to be able to use the USB that my car stereo has also, so if anyone finds out how that would be awsome

Hopefully I'm not too late to the party on this thread... First things first... I am running CM7 Ba2TF and am having a similar issue. Thanks for mentioning the various options you've tried, will save me from messing with it in my car.
There may be hope, though. When I mount the drive, I actually do get access to mp3s, yet they are on the ones on my internal memory card and not my external card like I am used to. I didn't see this particular quirk mentioned in your post so if you haven't tried that, it's certainly better than nothing.
If it's super duper important, I haven't had any issues with external SD card mounting in my car whenever I had a stock based rom, namely darkside and alien.
I have been googling around a bit on this and it looks like it might just be a rom issue. They can't all be perfect, I suppose, but try putting them on your internal card and see how that mounts.

[Q] Any Success with Vibrant and USB Head Units?

Hey Guys,
I figured you fine chaps at XDA would be the best to ask this compatibility question:
I'm planning on building a new car audio system but I'm concerned that the head unit I pick up will not support the Vibrant via USB. This is mostly because when I used it with my PC at home for the first time, I had to download Samsung USB drivers to get it to work. I can't imagine most head units having these drivers stock. Does anyone use their Vibrant with a head unit via USB?
Otherwise I may just have to wait until Parrot releases their Android powered unit and pray that it supports my phone.

Thanks for the help.
I actually just bought a new head unit that has a front usb port. Will test it after my nap. Yes, my nap and damn sure better be a good one.

What features are you, specifically, looking to use? If it's just to play mp3 files, I've read that this can work if you connect as mass storage.
For other audio functions, I'd just get a head unit with an auxillary port.
Bionix Frost
Dragon Kernel v5 Test4
I believe it will only play audio through the jack. If the part you have is usb im sure there are adapters you can get say at frys or radio shack.

Depends on what you need if it is the what is on the phone you need to access then, you can go and change the setting to mass storage and your phone will be seen as a flash drive. If you want to integrate the phone into the console system, you would need something that allowed that to happen, my Infiniti does do that to a point but then, I had to change some things around to make it to my liking. Don't know if that is helpful but it is more information
Cheers
If all you want to do is listen to music files that are on the sd card, I just tried it out and it works fine for that.

Yep, I'm just looking to play my mp3's from the SD card. I want to avoid the 3.5mm connection because I'm a bit of an audiophile. Thanks for all of the help guys.
Just get a Bluetooth Head unit, I use my vibrant to play music and talk on phone through bluetooth all day long...
best part...NO WIRES
I have had major issues with mounting as mass storage to my head unit. I was able to do this with my original Droid. My Thunderbolt gave me issues but when I flashed a ROM that did now auto mount a virtual cd drive it worked without any issues.
I have not been able to get my bionic to work. I have a ROM but it still mounts a cd drive as well as both SD cards.
Is there a way to stop the CD drive from mounting?
At this point when I mount the head unit picks it up but then loops through the sd card.
I am thinking it is not the head unit because I can connect either of my old phones and they will work without any issue.

[Q] Using phone as mp3 player in car

I used my evo 4g as my mp3 player for my car. Just plug it in to the usb and good to go. I tried it this morning w/ the lte, and it worked fine.
Got back in the car, and now no matter what, my head unit says "device error". the evo is set to disk drive, and i have rebooted multiple times. It did work this morning, so I cant imagine what the deal is.
So I tried taking out my sd card, and moving my songs around the phone using file explorer. It worked for a bit using connect as medai sync. Again, worked 1 time, then as soon as I pull the cord out and try again, nothing. Now my headunit either says device error or "no song". Sometimes the phone doesnt even give me the option to use as disk drive, just the htc sync.
So I finally loaded a rom. Worked great for 1 time. Now the same issues all over again? Any ideas on how to fix this? I'd rather not plug in anything made by apple into my car.
Do you have an aux in port? If so use it with an aux cord.

SD cards can become corrupted if the OS doesn't mount and unmount the drive properly. Try plugging your phone into a PC, and see if Windows/YourOS picks it up properly. Then unmount in Windows or on your phone (just switch to 'charge only').
See if that makes a difference.

The head unit is usb only. It is a mp3 player head unit. Meaning a usb cord runs to the front of my car for any device to plug in. Other devices work just fine. the evo 4g worked fine. This is the only device that just stops.

Yep, Windows picks it up just fine. It shows the sd card though, unless I use HTC sync. The same problem happens even if I have the mp3's on the phones internal storage, and not the sd card.
Head unit doesn't read MTP protocol for mounting. Most don't.

Excellent point - Honeycomb and ICS use MTP, whereas your OG EVO uses USB Mass Storage. I would check the documentation on your head unit, or contact their support, and you can probably confirm this.

If this is in fact the case....is there a device that I can purchase that I can put my sd card into that is USB Mass Storage? Like a simple cheap thing? I'm fine with just storing my music on the sd card and swapping it in and out of the phone.
You can use an external sd card and mount it. Tested on my wife's pioneer a few minutes ago, confirmed it read 236 mp3s and played through a few. Didn't seem to read the id3 tags though which is odd.
It will not read any off the internal card....

S3 usb to car stereo?

Am I correct that from what I have read...you can NOT plug your s3 into the usb of a car stereo and have it play and show song names etc? So unless they "fix" the usb mount issue the only options is aux or bluetooth? All the talk of the awesome sound these things are on paper anyways capable of and the purist connection to a car stereo is not available? Like many Im waiting for my US version to arrive in a couple of weeks and just trying to get a grip on what to expect and not expect is all.
Correct. You can't connect the S3 to a car stereo like a USB stick at the moment.
...unless your car stereo supports the MTP protocol
They have to be working to fix this right? I certainly hope they are....kind of hard to believe they made a change like this really.

I guess since Im switching from a iPhone I have just gotten use to being able to use the phone with just about anything I try to attach it to. I do not regret jumping to Android with this upcoming phone, Im done with apple, but I think its been long enough these guys need to get the ball rolling on more streamlined connectivity on a semi universal scale like the iphone has. I really dont want to have to keep the iphone around just so I can listen to my tunes in the car.
This irritates the faeces out of me.
Android File Manager on Mac is flakey with it. And now, I'm in work on my XP machine and I can't get files off of it.
Grrrr. Why the hell have they stopped USB Debugging from being able to mount as normal?! Or just have the "Mount on Next Connect" option like on the S2's ICS rollout (Which was annoying too, but at least it worked).
I just don't get why Google are doing stuff like this and stopping you install on external memory. Is Google starting to become like Apple where they just bend over to networks and developers so they can make as much money as possible while the customer suffers? If this is how they going I'm really not liking it.

I get the reason they dropped it for phones with only internal storage, but why doesn't the SGS3 support it with its external SD-CARD?
Has Samsung made any statements about this? Because all I know is not being able to connect to my car, tv, other computers etc. and not being able to transfer Apps to external memory is completely ruining this phone for me and can't use it the way I usually use Androids, I mean now I always have to carry around a flash drive and a OTG cable and transfer from phone to flash drive then flash drive to other device, and I really don't give a crap about their technical explanation because i'd rather have a rougher Android experience with all the features than what they doing here, and I shouldn't be having to Root my phone just to get stuff that should already be there.
I'm so mad! I just got a new deck today and it doesn't recognize my SGS3 via USB! :crying::crying::crying:
Has there been a fix since the last post?
Edit: I actually found a fix! Easy UMS! http://forum.xda-developers.com/showthread.php?t=1711009
Just get poweramp pro and a large sd-card, keep your music in .flac and sound quality is pretty decent even through the 3.5mil jack

Wireless SD Card reader as actual storage?

Hey guys, for ages now I've been looking at ways to wirelessly, or at least cleanly upgrading storage on the DNA, considering it has no SD card port, and I've been trying to stay away from Wi-Fi SD card readers considering that I know that if I'm on the road, I wouldn't be able to use internet considering that if I'm connected to the Wi-Fi SD card reader's hotspot, then I'd lose connectivity from LTE.
But, this product here interests me, http://www.kingston.com/us/wireless/wireless_readers#mlwg2 I saw some videos of it on Youtube playing back 4K videos instantaneously on an HTC One M7 with no lag, quality degrading, or anything(https://www.youtube.com/watch?v=GUGSKHQvtyU#t=332), it seems like a really nice product for storing music, hotswapping roms and what not, but, problem is, would there be any way for someone to actually download stuff to it like an actual means of storage?
I know about OTG cables and flash drives, I already have one of those, but I don't want to have this cable just dangling out of my phone as I'm gaming(assuming you can install apps to OTG storage) or listening to music. My question is, is there anyway to get these types of products to show up as ACTUAL SD Card storage in Settings? Or maybe there's some type of bluetooth SD card reader or so that could do so?
If not..my last resort is to actually use one of these things, but another problem is being away from Wi-Fi again. Is there any type of Xposed Module or anything of that nature that I can use to be connected to WiFi, but to use LTE connection instead? Thanks for reading and responses.
