[Q] Car Stereo Integration? - Android Q&A, Help & Troubleshooting

My car stereo supports USB thumb drives and iPods. My understanding is that this would work with UMS mode on Android (I think). But with ICS, UMS is gone and replaced by MTP and PTP. Is it possible to still connect an ICS android phone to a car stereo via USB?
I've got a Samsung Galaxy S3 and have tried using the "SGS3 Easy UMS" app to connect my phone with no luck. Is this on the right track? Has anyone else gotten this to work?
I've just switched over from an iPhone which worked great in the car for streaming music via USB and would like to do the same with my SGS3, but right now I can't seem to find a solution so I'm leaning towards returning it and going for the iPhone 5.
Anyone have any luck connecting an ICS android device to a car stereo via USB?
TIA!

Why don't you buy a 3.5 mm cable and connect it?

Unfortunately, this model stereo (Bose) does not have a 3.5mm input, it only has the USB input. The manual states that the USB input supports "various USB memory sticks, USB hard drives, and iPod players". I have been using it without issue with my iPhone 4 (both as a "USB drive" and to play streaming music via spotify and other streaming players). With the Android phone, with MTP, it doesn't look like a USB drive and therefore won't actually connect (I get a "check device" message).
Seems strange to me that with ICS, the OS is no longer compatible with any of these USB-enabled car stereos (and there seem to be only a handful of MTP-compatible head units out there). Since it apparently worked pre-ICS (I can't verify if that would work on my specific car stereo since my phone is ICS), it would seem that they could have at least had an option to enable UMS mode.
Still hoping for a solution...

I know how you feal i have a AVH-P3300T and it works GREAT with pandora and iPhone...(even an iPhone 2G) pandora detected the stereo as an accessory right away... but for what ever reason when i plug my HTC Sensation in it jsut reads it it as a disk drive..
there has to be some active driver letting the head unit and the device talk... If there was a way to capture that level of logging going on im sure there some people here that could reverse engineer this... and just make it so that its a service runnign in the back ground...
Either that... or soemoen figure out how to REPROGRAM a head unit from its stock image to an android image lol...

[Q] USB connect in 08' Jeep Grand Cherokee

I bought this car yesterday 01/04/12 and I noticed that it has a USB plug for my phone, so I connected my phone with my Jeep via USB and it does not recognize my phone. Just curious what I have to do to be able to connect the two. It would be pretty sweet because I can load up to 20 gb of storage on my cars hard drive and play music and view pictures and stuff.. so any help would be awesome.
Thank you!
Not likely that the Jeep will interface with your phone. USB ports in cars are generally for thumb drives that you put MP3 files on or for updating the Nav systems. Try calling a Jeep dealer for more info on what capabilities that USB port has.

Thank you, I'll just do it that way.
Might need to put the phone into USB storage mode - gotta tap on one of the notifications.
Can't help too much more - I haven't used USB mass storage mode in ages, being lazy I just adb push/pull.
Putting it in mass storage mode usually works. I haven't used it in a while either as I use bt now. But if you have an external card also the read time when you first plug it in could take a few min.

If it has a USB connection then mass storage should work for mp3's and some other music formats. It does in mine. If for some odd reason it doesn't you should check if it has bluetooth. You can then stream your music and/or do hands free calling

Well, I've got it connected via "UConnect". Does that also give me the ability to stream my music?

No. I also have an '08 Jeep GC with the Nav radio. In order to play music from the SG2 you will need to connect via AUX input. If you have the rear entertainment unit you can connect the SG2 to those inputs. (Of course you'll need a micro usb to RCA cable but you can get one custom made. Check the accessories thread as there is a member making them.) Else you'll need to connect the SG2 via the headphone jack to the 3.5" input on the radio. Another option is the Lockpick device for the NAV radio. You can google MyGIG Lockpick for more details.
Update: Here's the link to the thread for custom cable. Not sure if he's making anymore but you can check. I bought one and it works great.

[Q] Car Audio

So I drive a 2010 Nissan Sentra, which has a built in iPod/iPhone hookup to control audio through the steering wheel or stereo (has access to artists/albums/playlists/etc). Now, up until a couple days ago I kept an old iPod filled with music in my center console where the hookup cable was located and was able to play music fine. That iPod has been stolen from my car... wonderful.
So my question is this: Is the Droid Razr capable of playing audio through the micro usb port? I know If so, would something like this http://www.ebay.com/itm/Micro-USB-m...751409?pt=PDA_Accessories&hash=item2a223873b1 work to play music through my car via google play? My options are that or Aux (which means i cant safely change music while driving), seeing as my car does not support Bluetooth audio, and the iPod cable => car is proprietary, not USB. Would another option possibly be an iPod connector ==> Bluetooth, and connect my phone that way?
My Razr is Verizon running stock CM10.
I will try to keep this short.
First- usb ports in car audio will have different levels of support for devices. I usually work with aftermarket equipment as my cars are old, so this MIGHT not apply in your case. In a nutshell, if you plug in via usb, AND the car supports this, its going to try to approach the razr as if it were a usb flash drive, and attempt to read the music FILES you have in there. Two points here- this is NOT a direct audio stream, and thus will not send through audio from any apps on the phone, ie pandora or nav. Your steering controls will work, if this mode happens to work. Also, some stereos support this mode, but have the limitation of only seeing the first drive available and ignoring the others. The razr has two storages and it seems to present the internal first. Because of this the radio sometimes cant see your files.
In my case, my radio would only read the "wrong" partition, where none of my files were. I would up buying a cheap flash drive and leaving that in the radio, while my phone is docked on the windshield with an aux line running in so i can get pandora, etc.
Bluetooth is an option for me, but sounded terrible so i only use it for phone functions.

seeing as my car uses a proprietary port for iPod-in, not a USB port, your suggestions are not possible, but def appreciated. I wonder if the iPod 30pin ==> micro-USB will translate to reading the files off the phone as a mass storage in the manor you are suggesting. Thats going to require putting out some $ and downloading my files from the cloud, and then moving stuff around if its reading from the wrong location in the same way it was with your phone.

[Q] Any way to get Note 2 to work with Car USB?

I've been researching this for a few days now and I am disappointed that I can not find any way to get my Note 2 to allow music playback over USB through the car's USB port. I am trying to hook it up to a Mitsubishi MMCS system.
I know that Samsung has removed UMS on their new phones and that's what most car stereos are used for. I downloaded SGS3 Easy UMS and it seems to work fine (except for the phone appearing as read-only cd drive when I plug it into my computer), and I can access every folder on the device in this mode - at least on the computer. When I plug it into the USB in the car, it starts charging, but the USB/ipod mode on the NAV says "No connection". And yes, it works fine if I hook it up to my old iphone.
My phone has been rooted and I even unlocked it and installed this custom rom on the device, but I still am at a no go. Unfortunately, using my phone as a media device for my car stereo on my long trips to work is one of the main functions I use my phone for. Right now I am stuck using bluetooth which has horrible quality and doesn't offer near the same amount of features on the stereo as USB does.
Does anyone have any ideas or am I simply hosed?

[Q] Choosing Android tablet to work in Car

Trying to figure out how to get a working Android tablet to play in my car's USB port. Apparently the SGS3 Easy UMS app works, where you are able to play music through the car using that app, as it has a sim card slot to fix the issue where usually the car will say device not supported, as is my issue with the Nexus 4.
I was trying to get a Nexus 7 tablet installed in my car, without redoing all the stereos etc. to get USB sound, but it seems that may be the only way to go. I really want a USB connection, and not Bluetooth / Aux, as the sound quality is inferior...
Car: Chevy Cruze 2012
Tablet of choice: Nexus 7, but may go with a Galaxy Tab, if I'd be able to use USB that way.
Hopefully this is the right place to ask this question...
Forgot to mention I plan on using this as my car's dash, and remove the stock radio / navigation.

Honor 7 is not working with my car audio kenwood kmm u11.

Hello folks.
I bought this phone 3weeks ago and I can't use it with my kenwood kmm u11 car audio. When I connect my phone via usb to car audio, files are being read but sound is coming from the phone instead of car's speakers. Also I have tried it with some other car audios and it did not worked. My phone has B370 build and I could not find a solution for this situation. Please help me if anyone has a solution.
It can't work as a USB mass storage device as the radio doesn't have the right protocols.
When you connect it to a windows PC, it install drivers. A radio can't do that.
Sound only through BT or 3,5"mm jack.

I have an LG G2 and it works with usb connection. What is the difference? Honor 7 and LG G2 have Android 5.0.2. I can't get the point.

USB works like any other mass storage device. Might be compatible or not. The the device that's accessing the files plays and handles the output.
The car radio could have a protocol to control through USB the android music player. Check if H7's music player is working. There's also a similar protocol for iOS.
Finally, there's only 5 ways of getting audio out from Android, to other than built-in speaker:
1- 3,5" jack audio out (headphones but works with anything)
2- MHL, for compatible devices, but audio is automatically routed
3- HDMI out, audio automatically routed.
4- Bluetooth, audio automatically routed.
5- Wi-Fi cast, audio automatically routed.
You can use USB as an audio output, but you have to fiddle with the OS. And I'm not sure if it's possible with all devices.
@blast4620 some devices have inbuilt Mass Storage mode, but Honor 7 just have MTP protocol and no Mass Storage protocol.
MTP protocol requires some drivers to be installed on the device to which you are connecting your phone, so it can't work on your Kenwood Player.
Whereas Mass Storage mode doesn't require any drivers to be installed, it's just like Plug & Play(A USB Pen-Drive). So, your LG phone must have a Mass Storage mode, but Honor 7 doesn't have it.
I hope this helps.
