O.k. this is my first thread on XDA, gotta say...love this site! Heres my request. I have a Pioneer Z110BT nav unit in my car which supports AVRCP 1.3 to allow track and artist text to be pushed while streaming audio over bluetooth. However I think the EVO only uses version 1.0, so I'm only able to use the pause, play, stop, ff, and rewind features on the nav unit. I saw somewhere that eclair added some support for version 1.3. Is there any chance of someone getting AVRCP 1.3 working on the EVO?
AVRCP only works sometimes
Alright I'm bringing the thread back from the dead because I'm having bluetooth problems myself. The problem is my AVRCP (the bluetooth function that allows external control of songs) only works sometimes with my bluetooth car stereo (Sony Xplod MEX-BT2900 and my Sony Xplod MEX-BT2800). I get into my car with the bluetooth radio on my stereo and my phone, the phone will connect completely (media and phone), but I will not be able to control music playback function from my cd player or steerling wheel control. Then I will do a complete soft reset and the AVRCP will work flawlessly (i have complete control of playback without touching the phone). My question is why does this do this? Why does it only want to work sometimes and not others? You can see my setup below. I do have Pandora installed but I went into settings and selected Bluetooth for Automotive (OFF). I'm using music installed to my SD card through the stock htc sense 1.0 music app. I have not tried google music or anything like that. I do have tune-in radio and iheartradio installed. It has done this for a bunch of different Rom's and kernels including stock. Is the stock sense bluetooth profile garbage or what?
I don't believe its your phone I have the same issue with a Droid x 2 and the bt2900. Mine will also leave a paused message on the head unit with music playing. I believe its a Sony issue.
does anyone know of any models of car stereo that you can hook a g2 into and control the g2's music player (or that has a corresponding separate music playing app that is controllable at least). i'd like to be able to hook up my phone by usb and then use the deck controls (or even better the controls on my wheel) to skip forward / back / pause, etc.
i've been searching and everything says "ipod/iphone" compatible and nothing mentions android. at best they say that the music will play thru via usb, but not whether or not you'll actually be able to control the music too.
thanks for the info

The Desire Z works with all (the) cars (I have tried) that have Bluetooth. You have to switch to BT Audio not just BT Phone, but then the controls work just fine.
Pretty much ANY USB automotive HU will work fine. It does NOT play music through the USB as fruitjunk does though... you plug the phone in, enable MASS STORAGE MODE, and use the HU to browse/select/play the mp3 file. The audio decoding happens in the HU, not the phone. No need to do things the iDiot way.
Alternatively, you need a BT HU that supports AVRCP, then you can use the HU to control the phone's media application.
thanks
hey thanks to both of you. great info. just out of curiosity, do you guys actually use these features? and what head unit are you using?
thanks
I use a Sony bt3600u stereo that works fine with BT. Allows pausing/Playing, Skipping forwards & backwards of tracks on the stock music app.
Doesn't display track names etc (Just says 'BT Audio') but that doesn't bother me.
This is my stereo: Link
Hope that helps
I would like to build an Android car infotainment device to replace all my gadgets inside the car. One option would be a micro PC with USB touchscreen and a lot of devices connected via USB. The other one would be an Android gadget, either small tablet or TV box.
The biggest question I have is: what Android devices support 5.1 audio? This is a must, though I actually can use only 4 channels. What audio formats are supported for this?
The other question would be TMC - the FM kind, not online.
Are there any embedded platforms out there (except PC and Android) which support multi-channel audio?
Has anyone done this before? I might be reinventing the wheel.
No updates? Either nobody knows about Android 5.1 sound output or they are working under NDAs.
Are you planning on keeping a headunit to control volume, do you want am/fm radio, etc....
without a headunit you will need an amp where you can use the headphone to rca adapter and usually its the amp that would add front and rear to the left/right output of your android device so you would still get the 4 chan output effect. to go for the 5.1 chan you will need another device that actually controls the 5 speakers plus the subwoofer which might be tricky but I'm sure its not impossible.
the setup I was going to go with was a amp that I can mount its power controls (left right front back and volume) (or amp/eq combo) to where I can reach it and build a mount for a 7in (possibly diff size not sure depends on how it will look) and use the heaphone to rca adapter to power the audio and put the usb inside the dash possibly with a little hub if they make it (that way not only is it getting power from it, if it allows, the addition of say a thumb drive with added music/movies. some tablets/phones have fm radios built in as long as something is plugged into the headphone jack (my new phone doesn't seem to have it but thats a feature I will be looking for in a tablet)
4chan amp
eq that would allow 2 chan in and 4 chan out plus sub out (if you have a separate sub amp)
I just want to know if there are any android devices that are able to stream 5.1, I can take it from there. Same question about TMC support.
Some details:
My car is already fitted from the factory with 4 channel preamp and 12 speakers including subwoofer low-pass. It has low-level input for those channels, worst case I would buy a preamp.
FM is pretty much given on most Android devices, probably excluding some tablets, but I won't actually miss it if it's not there.
TMC would be nice since all Androids usually have a GPS sensor and sometimes compass.
Anyway, it was mostly a request for suggestions or even a rant - I'm surprised that something like this doesn't exist yet. With the exception of dedicated units going >$$$-$$$$, an alternative set-up would be a medium-range blueray player coupled with an Android tablet. Music control could be set up with DLNA, bluetooth streaming or mixing player and android audio would be a bit harder but not impossible.
hey friends
this is a nice thought and you are absolutely great.
this is wonderful thread

Great Idea
Hi,
Currently I'm also thinking about installing an android tablet in my car to have music, navigation, movie player, speed camera warning, etc. But the biggest problem is the sound. I want to connect tablet with car audio using jack-jack cable. Everything is fine till the AUX source is selected in car audio device, but when I switch it to Tuner or CD - the sound from tablet is cutted off, so e.g. navigation announcement are not heard.
Any suggestions for this issue?
audio rom
its a shame that there are many many roms but none fur special purposes like this.
we need a car rom

Only solution can see is to run the audio from the tablet alone. I.e. use the tablet to provide both radio tuner AND navigation. You will end up using the car system purely as an amplifier.

This would be what I would do in this situation. Or just unplug the audio cable from the tablet when using other radio options so the navigation will come through the tablet's speakers.
I want to do something similar but rather than purchase a new device I want to use my Note2. No head unit at all. The Note2 would likely be dedicated to this use and I'd get a different phone to use as, well, a phone.
For sound I was hoping I could use USB OTG to connect a USB sound card with 5.1 output but I'm not sure if this would work. I want to use the sound card instead of audio direct out of the headphone jack because that reduces my connected cables to just one (easier) and should provide at least 4 channel output which eliminates the need for another device to control volume, fader, and balance.
For radio I was going to use SDR for AM/FM (and more) via a cheap USB TV tuner.

Where I'm stuck now is that I'd like to be able to connect an iProduct (iPhone/iPod) like you can to most car radios and control/stream music from the iProduct, via the Android Note2 using USB OTG again. I cannot find how to do this but the Parrot Asteroid Smart runs Android and it seems to be able to do it so it must be possible.

Any info anyone can provide regarding the sound card and iPod integration would be highly appreciated.
You can go wireless and use some AirPlay receiver for Android.
I don't know about wired solutions, the classic iPod connector has ~30 pins and some of them are used for audio and some of them are used for serial-like playlist control plus current track information.

It's just a USB to iPod cable that they use for everything else... Parrot Asteroid Smart that I linked to has it as do most modern stock head units.
Did a little more googling and it seems several companies sell android head units that support iPod.
Why don't you use a USB DAC? There are a few out there that are surround sound capable.
Out from the DAC into an eq preamp and out to your existing amplifier. The eq preamp has main volume controls as well as sub control with dedicated output.
Also there are head units out there that are just "receivers" capable of accepting a digital inputs and outputting 5.1 signal via RCA.
I installed a nexus 7 2013 in my VW, currently using Bluetooth to connect to a receiver where it the outputs to an rca input on my deck that was relocated to my glovebox. I am planning on replacing the Bluetooth adaptor with a USB DAC in order to achieve a higher quality sound.
I am currently doing a similar install in a 2010 charger, a deck will not be used however as I will be using the DAC method with an eq and output to the factory amp. I considered going the android TV box route as I have a MINIX box, but there is some work involved in getting the touchscreen to function properly as it is not set up for this out of the box.
You can purchase a double din deck from eBay (I stumbled across it a few days ago but didn't write the link down) it has a dual os system. It uses android for the car audio function and windows for the car PC function. Not sure how well it works but it got reasonable reviews.
Edit: ...and once again I answer without reading the whole thread...:silly:
Is it somehow easier to get all the various apps on the phone to output audio to a DAC than a USB sound card?

I believe when the device detects a DAC (must use an otg cable BTW) it automatically re routes all audio out the USB. You can disable automatic USB audio routing in developer settings.

That sounds easier. Thanks for the tip.
Well I can't find any information regarding the iPod integration and I've found next to nothing for DVD video and audio CD playback and radio and backup camera functionality would also take some mucking about so it looks like I'd probably be better off buying something like this:
http://www.ebay.com/itm/7-Android-4...621?pt=LH_DefaultDomain_0&hash=item2a31320af5
Which has it all sorted out already. So much for that fun idea. No idea what apps they use for all that stuff.

That unit looks slow at only dual-core. It will probably be sluggish when multi-tasking.
The main chip probably supports several I2S devices (aux in/adc, tuner/adc, DVD) and routing plus demuxing is done via linux hardware control.
The DVD player and tuner probably support the i2c or spi protocol to control seeking and other functions. This is again controllable via the linux devices.
Usually the consumer devices don't have these easily exposed and it's probably a non-trivial task to piggyback on existing hardware, assuming the needed connections are broken out on the board. As far as I can see the only Android devices with CD or DVD are the car players like above.
Another option would be to take the sound from the HDMI signal. A DVD player/tuner can be wired in parallel with an HDMI switcher. However controlling the tracks would not be easy, it would require emulating the remote with an IR transmitter.
Sorry for the long title,
I got a new car this week, Honda Civic Tourer Uk/Ireland model
The phone paired fine and i can stream music no problem but i cant 'browse' music from the stereo's controls like i can with an ipod. When i browse to the phone via the stereo it just gives me device name. I can skip tracks forward or back, but cant change albums etc with the car controls
Anyone else come across this? On 4.3 update
Cheers,
Mick

Most likely its just htc's software which doesn't support that feature in your car like it does with your ipod.
Would it be worth converting to Google play edition to see if it would work?
Flashed GPE rom and no difference... can just see the device name from the cars stereo and forward back tracks but cant browse.. its not that big of a deal but still would be nice to have working. I'm figuring the stereo must be missing something for it to work..
I have the same problem with my BMW Business Media.With my missus iphone 5S,I can browse music directory as MTP connection,cant see the album art but can see next song,all directory as albums etc.
I am just wondering has anybody come up with a solution for it?
There are so many options that I don't know where to begin.
In fact, I'm rather lost as I can't really tell if a combination of tablet + car stereo will work for what I want to achieve.
Here's what I want to do:
I am using a Samsung Galaxy Tab 3 8" as a satnav with Sygic.
I currently have an old Pioneer car stereo which works perfectly fine for mp3 CDs and radio but I want to change it to a new unit that would accept a small USB drive as storage for my mp3's. I don't care if it will accept CD's or not (even better if it doesn't).
What I want is this new unit to allow me to play music or radio as normal and, when instructions come from the Sygic App (turn left, turn right etc) during navigation, to get the music interrupted and the instructions heard from the car's speakers. After the instructions are over, the music then start back automatically.
The only thing I managed to sort out is that, for this whole thing to work, both devices (tablet and car stereo) must support the A2DP protocol. The Samsung Galaxy Tab 3 8" does indeed support A2DP for Bluetooth (according to specs) but I'm lost as far as car stereos are concerned.
Instead of looking the specs of every single car stereo available on the market today, I thought I would try asking here first.
Does anyone have anything similar working?
Thanks in advance

You may try the "Dynavin Car Stereo"
