Hi all, first post but I'm really curious about this. I have a Droid Incredible and a 2008 Corolla with the factory radio. I added an aux-in 3.5 mm jack (several actually) to the head unit using one of the standard kits that plugs into the CD changer port on the back of the radio. This works well, although I had to get some mini TRS-TRRS 3.5 adapters to stop the Incredible from having the problem where it thinks it's getting headset commands through a TRS headset plug and goes crazy.
The thing that I would love is if I could control my Incredible with the buttons on the head unit, at least to have the ability to skip tracks forward/back by pushing the radio buttons. As far as I can tell, this should be possible given the hardware. There are kits that use the CD changer port on the radio to control an iPod, so we know we can get the track forward/back buttons sent out. And we know the Incredible will take headset commands like play/pause, answer, voice dial, and track forward through the headphone jack (I know this partly because these are the things my Incredible does when it is going crazy from the TRS input).
So is there no adapter that will connect to my car radio CD changer port and send the radio button pushes out as TRRS headset commands? I am really surprised this doesn't exist, but have searched around the web to no avail. Considering trying to build something but I don't have experience with an electronics project of this scale.
Alternatively, there is probably going to be an audio in/out + remote control for the Incredible usb adapter at some point, like the one for the Droid Eris. I assume this will be available since we know the Incredible is wired for audio through the USB port (I know this from the videos online where the Incredible does video out with audio through the USB). So this would appear to be another option for running the car radio commands into the phone.
Okay, barring any device surfacing to handle this, I'm going ahead with some research of my own. Apparently one reason devices and information are not widely available is that Apple may have a patent on some forms of headset commands through the TRRS 3.5 or 2.5 mm jack. Since I'm a new forum user I can't post any links out right now; sorry.
I have a SkullCandy headphones+mic. They have a single button next to the mic. This button works to pause/play the Meridian music player on my Droid Incredible. Pushing the button twice rapidly pauses and then skips to the next track and plays. If I push the button when no music player is open, it opens Meridian and plays. If I push when some other music player is open, it opens Meridian and plays.
Presumably the button works by changing the resistance over the headphone wires. Checking the resistance between the sleeve (which seems to be ground) and the other contacts (Tip, Ring1, Ring2) I find that without the button pressed, the resistance is about 1 kOhm for all three. Pushing the button changes the resistances to be: 17 Ohm, 17 Ohm, 1 Ohm for the Tip, Ring1, Ring2 respectively.
So if I can figure out what the head unit sends to the CD changer when the radio buttons are pushed, I may be able to rig up something useful. I am still curious what other signals might be possible. When I have the shorting out going crazy behavior there definitely seems to be a case where it opens the voice dialer window or calls the last number in the call list. Not clear whether this is a different hardware signal or something about the software state of the phone when it gets the resistance change. Haven't yet tested what happens when you push the button and there is a call, but presumably it answers/hangs up. There are other headsets (for Apple players mostly) that have additional buttons too; not sure if that's relevant.
Hmm, I need a headunit for the same functions.
AFAIK for controllling a smartphone over bluetooth it must support AVRCP for controlling and A2DP for audio.
So I found this unit: Sony MEX-BT3800U
Iam going to buy this soon (need to sell some stuff).
Hope this runs with my Kaiser
@sda2: that one looks pretty good! A little pricey for me and I kind of like the aesthetic of having the factory radio but just having it do more. Keeps my car looking cheap and not theft-worthy.
I have confirmed that pretty much everything I've seen the phone do in response to headset commands is just dependent on the context the OS/software is in. So other than the single click or double click there doesn't seem to be a lot more that the phone is expecting to handle.
However, I did find an app called DroidShuffle that allows you to assign more functions to things like a long click or a triple click. Sadly, I couldn't get this app to work with my setup on the Incredible. But I think it is an interesting concept; since the OS only seems to understand 1 type of click, just write a service that lets it respond differently to different numbers or duration of click. Then setup a circuit that converts the different car radio head unit button pushes into these differentiable click trains.
Don't think I'm going to put the time in though; will wait to see what kind of control you can get through the micro-USB.
Another possibility: a device to convert the head unit button pushes to bluetooth AVRCP. This might be more widely useful, but I think the complexity and cost versus a wired solution push it towards the point where just getting a new head unit makes more sense. Unless I can find a simple generic AVRCP chip...
I think what you're looking for is something like this? It comes with a wireless strap that you can put on your steering wheel that gives you control over your device. Basic stuff like answering phone, play music, and move track forward and back. Plus, it uses a 3.5mm port, so no stupid bad quality FM radio. As long as Bluetooth is enabled, it automatically connects to the device. So all you gotta do is walk into the car.
BTW, I have this hooked up to my Pioneer stereo, using the P-BUS that all Pioneers have. I just needed a adapter. Not to confuse anyone, this needs a car stereo with a 3.5mm aux jack. You can usually get an adapter that plugs in the back where the CD changer would normally go, and avoid the terrible FM radio quality. Don't waste your time with FM radio adapters.

@DukeNukem: This looks nice; I especially like the steering wheel remote. I am still going to play with decoding the output from the head unit buttons, and I ordered a microcontroller and bluetooth module to see if I can actually get it speaking AVRCP without giving myself a stroke. But that has moved into fun project land so I think your suggestion will be the practical solution, especially if I can find it for < $50.
yeah i also need that for my relative who has the same problem about the Car radio head unit that sends headset commands
thanks!!
Well, I bought a Really Bare Bones Board (Arduino compatible that's small, cheap, and easy to breadboard) from Modern Device. Based on several Corolla AVCLAN sniffing projects out there on the web (Marcin, SigmaObjects, AngryCamel) it was pretty easy to get something up and running that sniffs the bus for head unit messages.
Since I already paid the $50 for the box that emulates a CD changer to add aux-in, I don't need to worry about that, but it should be pretty easy to accomplish that with the microcontroller as well.
For sending headset commands through the 3.5 mm jack, I think I'm pretty close. Not exactly sure how to emulate a click on the headset button, but I would guess a simple transistor can do the job since it's basically just a change in resistance.
I bought a bluetooth chip though, so I am trying to get messages to my phone through that for now. There is a post on android forums where someone has hacked the pinout for the USB/AV port on the Droid Incredible too, so I'm hoping it will be possible to send commands through that at some time soon.
Will plan to post project details at some point, but it's still a work in progress for now.
You can try with this one:
mytrendyphone.co.uk
Clarion DXZ588RUSB USB/MP3 Radio - Black
Okay, I have a simple version essentially working: can capture commands from the car radio and signal simple headset clicks to the smartphone. Haven't written the software to link everything up yet; will post when that's done.

http://fritzing.org/projects/cellphone-headset-clicker/
It should be fairly trivial to modify VWCDPIC (for Audi / Volkswagen / SEAT / Skoda) etc, to do this. I may look into doing this for my HTC HD2 soon, if no-one has done this yet.
For emulating the button pushes, on the TRRS I think you should just connect the lines to each TRR, and just leave them in input mode (high resistance). Then when you want to send a command, just pull the line down to ground. If you're worried about applying too much resistance, add a resistor between the micro and the tip or ring.
On my HTC headset:
Play/Pause/Phone - Pull the second ring down to ground (Mic line)
Previous Track - Pull the first ring down from 20kOhm to ~235 Ohm
Next Track - Pull the tip from 20kOhm to ~600 Ohm
Thanks for that futaris; I'll check out whether I get different behaviors for pulling different lines to ground.
Hallo,
I have in my car VWCDPIC working with my android HTC desire phone, but now without remote control of this phone. For me is enough implement jump between tags and play/stop function - so the same functions which I have on headset for my phone.
I checked firmware which is here :
http://www.k9spud.com/vwcdpic/devel/vwcdpic3/flash/
and checked source code. I found inside source code this information :
; VWCDPIC Volkswagen CMR PIC16F627(a)/PIC16F628(a) Connections
;--------------------------------------------------------------------------
; PIC RA3 -> VW Pin 2 Clock to Head Unit
; PIC RA2 -> VW Pin 1 Data to Head Unit
; PIC RB0 <- VW Pin 4 Data from Head Unit
; Make sure PIC and VW Head Unit have common GND.
;
; PIC RB6 -> PJRC MP3 Player RX (19.2Kbps serial)
; PIC RB7 -> Archos Jukebox RX (9600bps serial with weak pull-up)
; Make sure PIC and MP3 Player have common GND.
;
; Volkswagen CMR:
; PIC RB1 -> TP11 when button Mix is pressed has about 15
; seconds logic low output (one pulse)
; ALSO:
; when soft-button CD6 is pressed, TP11 has
; about 3 seconds logic low output (one pulse)
; FINALLY:
; when button SCAN is pressed, TP11 has about 20ms
; logic low output (one pulse)
;
; PIC RB2 -> TP14 when button Next Track (>>) is pressed, has
; about 20ms logic low output (one pulse)
;
; PIC RB3 -> TP15 when button Last Track (<<) is pressed, TP15
; has about 20ms logic low output (one pulse)
;
; PIC RB4 -> Track number is incremented when one pulse (low active) on RB4
;
; PIC RB5 -> Track number is decremented when one pulse (low active) on RB5
Important information is that on RB2 and RB3 is pulse after next/last track pressing. But it's for PIC16F627 with 16pins.
What I need is modify this firmware for PIC12F629 which is now connected :
; VWCDPIC 3.x PIC12F629/PIC12F675/PIC12F683 Connections
;--------------------------------------------------------------------------
; PIC GP0 -> VW Pin 2 Clock to Head Unit
; PIC GP1 -> VW Pin 1 Data to Head Unit
; PIC GP2 <- VW Pin 4 Data from Head Unit
; Make sure PIC and VW Head Unit have common GND.
;
; PIC GP4 -> PJRC MP3 Player RX (19.2Kbps serial)
; PIC GP5 -> Archos Jukebox RX (9600bps serial with weak pull-up)
; Make sure PIC and MP3 Player have common GND.
so I want cancel GP4 and GP5 - I don't need this serial communication and on GP3, GP4, GP5 I need next/last track pulse and play/stop pulse.
Is there somebody who is able change program and implement it ?
Thanks

You guys inspired me to look deeper into this. I found a few potential solutions. I am not one to really spend a lot of money on this type of stuff, but there is one heck of a solutions commercially available:
(can't post a link, but lookup Scosche BT1200)
If you click on the download link and look at the instructions, you can really see how this thing works. It is a pretty elegant solution, but then again you pay for it as well. I like that it allows BT streaming or direct connect.
It seems to me that the whole reason this stuff is so hard to find is due to Apple's longtime patent of a way of controlling portable audio devices. I am not sure what the specifics are, but you certainly don't see anyone making a nice adapter/connector from iPod to TRRS that codes these commands for TRRS signaling. My fiance has a car with play/pause, volume controls on the steering wheel, and I would love to have it all work with a generic mp3 player, but unfortunately it is set to work with an iPod, and there doesn't seem to be any other way about it. It is almost like consumers are being bullied by these patents. I want the functionality, but I am not going to be stuck with buying from that brand.
I think that best way is firmware modification as posted futaris , but I don't have enough skills to do that. Or is some modificaton for HTC phones ( and not only HTC - it's only about resistance ) available now ?

I have tried to pair two different bluetooth media controllers but neither will connect. I see them as available in the devices list but when I click connect nothing happens. I assume if I can see them in the list even the funky bt setup on this thing can use it or is that not correct?
I have a joying UQ124 its the no cd quad core version if it helps
Have you read this?
http://forum.xda-developers.com/and...head-units-qa/bluetooth-media-remote-t3283162
I did but was hoping someone had better results. Also, I was confused about the person who said they resolved an issue by using and xposed module. I didn't find any module that looks related to bt in a relevant way and was not sure if they were even having the same problem.
I guess I just want to know if this is even possable with this headunit or if I should keep looking for a solution.

I'm not sure exactly what you're trying to do with your specific bluetooth controllers, but if you are unable to get them to work as intended, consider the back-lit version of the Lenovo N5902 or something similar for multimedia control of your JY unit. The N5902 works well as a multimedia remote for Android or Windows home theater multimedia systems as well as Android head units. All you'll need is an open usb port for the small wireless dongle and you'll be good to go.

Ideally I would like to use something like
amazon /iSimple-Portable-Wireless-Smartphones-Bluetooth/dp/B00KPZN5UC/ref=pd_sim_107_2?ie=UTF8&dpID=411ue0yFG3L&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=0QC6Y0SC8ZEF13W3638N
So I can have the controlls on the wheel, but I guess my underlying question is will the unit work with bt devices besides a phone and obd.

I have to admit the Axxess RFASWC has worked out well for what it is, however I am currently waiting for a BMW I-Drive and an Arduino Leonardo board with in built CAN BUS to arrive.
Planning to write some software to convert the CAN BUS messages from the I-Drive into USB HID Remote commands.

Please note that I've only installed one of these units on a Joying JY-UQ124, and 6 out of the 7 buttons work correctly. The lower right call button does not register any signal in the JY SWC settings, so I'm guessing the button is defective. That stated, it's been about two weeks since requesting help from the ebay seller, and I'm still waiting for a reply on this specific inoperative button issue. Hopefully, the delayed reply is only due to the long Chinese New Year holiday.

I went ahead and ordered one of these because for the price I think it will do really close to everything I want. I will let you know if my button works in case it is just a design problem, save you trouble dealing with vendor. Of course, it may take a month to get here =/

Totally possible, infact the bluetooth version has been done already http://www.volcano.at/iDrive/
The iDrive controller and arduino arrived earlier today and only played around with then for half an hour making sure they were working, so far managed to receive lots of CAN BUS raw data.
I have also downloaded a shed load of BMW CAN BUS codes that I have yet to go through, but my initial thought is to try sending the code to impersonate turning the lights on to see which set turns on the key backlights.
Once i have more time I will get a better understanding about how the CAN BUS side of things work, and hopefully do what I want to do.
Just thought I would do a quick update on getting the BMW IDrive working with the Head Unit.
most things that i want it to do works, but the rotary part of the control, for some reason I cant get that to initialise and start sending messages when twisted.
Whats working..
Stick press -> Play/Pause
Stick left/right -> prev/next track
Stick up/down -> vol up/down
Menu -> home
Back -> back
Media -> sends shortcut keypress that starts amazon music
Radio -> sends shortcut keypress that starts the radio
Tel -> sends shortcut keypress that starts bluetooth
Nav -> sends shortcut keypress that starts Here nav
Option -> i keep a record of the last shortcut and it starts the next in line (Amazon Music>Radio>Bluetooth>nav)
What i need to do..
Enable long press for left/right -> fastforward/rewind
Enable long press for up/down -> continuous volume up and down until i release it.
and the damn rotary control lol.
adding a sensor that detects the brightness of my dash lights and alters the controller led brightness, at present i just have it set to 50% brightness all the time.

Yes, very nice implementation by hobbytronics, the HU thinks it is connected with both a USB HID Keyboard, and a USB HID Remote.
USB Keyboard starts the default apps i have setup with https://play.google.com/store/apps/details?id=com.apedroid.hwkeyboardhelper&hl=en and takes care of HOME (Menu), BACK (Back), and Switching between recent apps with the option button.
USB Remote takes care of Pev, Next, Play/Pause, Volume, etc..
Once i have it all working I will post the code up here.

Can you give me the wiring that you used on your Joying? I ordered one and the box came with Chinese instructions. While the seller attempted to send me an english doc, so far the attempts have resulted in documents that have been too small to be useful.

I honestly dont remember. I stripped the wires on the stereo and on the remote receiver and was just going to try it one way and if it didnt work, try it the other. It ended up working the first way so I put connectors on the end to make the connection permanent and called it a day. I doubt it would hurt if you had it backwards.
[edit] Obviously red is 12v and black is ground. I used the google translate app to translate the directions, they gave me some info. It uses your phone camera to translate written language.
Hi,
Ik use Malaysk rom (version RK3188) on an seicaneunit in my Mini Cooper R56.
I have some issue's/problems which i cannot solve or get an aswer to...
1.
I want to run the app 'flitsmeister' (a app for traffic info and speed traps warnings). This apps runs in background and popups when it detects traffic or a speed trap, this works OK. But when i start it on boot it stays on top until i press home etc. I would like to start this app on boot and it should run in the background or the home button should be 'pressed' automaticly after a few seconds.
Is there a way to do this in this rom?!
2.
I cannot change the steering buttons control, when i open the menu and press the key to assign it simply performs the default assigned function, i cannot change this in anyway. How can i change the behavour of the steering wheel controls and save this?
3.
Is there a update for a newer android version (5 or 6) for this unit which i can use?
Steerling wheel functionality works through a canbus which most newer cars have. Seicane eonon etc all use canbus.. however thats if your vehicle have one which it should. Problem one.. your missing a canbus..
If you have a canbus 2 issues possible.
Canbus is picky and eah make speaks their own language.. now most chinese aftermarket HU use a multi purpose canbus decoder which your vehicle may not pick up or you have a faulty canbus.
2. Canbus wiring.. now alot of makes run wiring through the oem harness.. depending the hu in the modle of car.. like running a stock crappy system vs an alpine, inifinte, bode system where multipul components talk.. but that then becomes a sound issues differet topic.
The canbus wiring itself could be wrong off the new HU harness you'll have to check seicanes crappy wiring diagram matching to your oem harness. Where the canbus connection is use a multimeter with the car off.., on accessory and started.
Future reference..
Seicane eonon etc have messed up the wiring giving the canbud power even when the car is off.. meaning they ran the power off the battery live wire.. vs just the accessory and on power wire.. draining the battery of your vehicle. Simple fix youll have to just switch the power wire to the correct wire being accessories and on.
At the end of the day you most likely need the canbus for the steering wheel functions to work. Ifcyou have it do soke trouble shooting
I have a Gromaudio USB3 interface on my car, first those unfamiliar with it, the interface connects to the CD changer port of the head unit from the car, and it will act as a CD changer emulator.
On the input side it has a USB port where you can Android device and stream any audio source via USB through the head unit of the car.
Steering wheel buttons works to control your Android device also or it should.
And this is the main issue I'm writing this.
It seem to be something "special" with this HTC 10 device. Because only the volume Steering wheel controls works but the next and prev doesn't.
If I use the Grom audio application DashLinQ I can control these music from my device, the next and prev buttons will work also.
But it doesn't work with other 3rd party apps like Soundcloud or Poweramp.
And this seem to not work with HTC 10 only. Mine has 7.x Android OS, Maximus HD ROM.
With other Android phones everything workes fine, Samsung S7, HTC One M7 with Google edition android.
Any idea what HTC does special on HTC10 to block this kind of control?
If I use Poweramp and try next button on the steering wheel the music stops for 1 sec but it resumes without changing the track. Is like the command from the steering wheel reaches the phone but the phone does not execute it.
Any idea what does HTC special on this phone or how to debug this?
Nobody, anything?

Hello all!
Edit: if you're not interested in the Story, and just want the solution, scroll to Chapter Four
This already has been quite the journey, in fact I went way deeper down this rabbit hole than I'd like to admit, so here is the story:
General info:
Car: Audi TT mk2, 2011, has Bose audio and hands free talking, previous stereo was the RNS-E
Headunit: Xtrons PB78ATTRP, PX5
So the problem was/is, the unit only outputs Sound in these apps:
-Radio, A2DP, Phone Calls, CD-Player, Music or Videos that are loaded onto the micro-SD
I contacted the Xtrons support, apart from being very unhelpful and not doing anything, I later got them to send me a new can bus-adapter (will come into play further down).
So because they weren't very helpful, and i really liked the unit, and with basically no alternatives (Xtrons units claim to be plug+play with the Bose systems, which no other manufacturer I came across claimed), I decided I'd try to hunt it down myself.
Chapter one: Updated the unit to the newest Xtrons firmware + MCU, that did nothing. Updated it to lots of different MCUs, didn't do anything either. Installed Hal9k, no change. Different MCU again, no change. Went on many searches on google, and found people with similar/same problems, but no solution. Then came across something entirely different ,but it gave me new ideas.
Chapter two: I reset the unit a few times, back to Xtrons, back to Hal9k, no change, then I came across the factory settings: you can access those in the car settings all the way down, then enter 126. Standard setting for the can bus profile was, I think, 23 AudiA3, A4. Changed it to anything different than that, and voila, sound now works like it should (although the Bose amp is now always on, when the stereo is on, giving out a little white noise). However, a new enemy emerged: now the steering wheel controls, of course, stopped working.
Chapter three: Tried many different settings in the factory-can bus settings, of course, no difference. At this point, I figured the only thing that could be wrong is either the can bus decoder box or the MCU. So I got that new box from Xtrons, and nothing changed. More internet search fopllowed: I found out some MCUs work across different manufacturers, Xtrons being "GS" for example. So I tried some different ones, and found my can bus box, being a "GS", wouldn't speak with those MCUs. At this point, I got sick of it and figured I'd learn to live without steering wheel controls.
Chapter four: a month or two after chapter three (Today), I figured why not give it another try. So I did another google research on people with can bus problems on PX5 and found this Thread.
So i did what he did, and: IT WORKS! (sort of) Now I have sound in all Apps, and working steering wheel controls. The amp is still constantly on and makes white noise when no music is playing, and i cant completely disable the can bus app, only force stop it, resulting in probably having to force stop it if it somehow starts itself or the unit reboots (if it only sleeps it's fine).
So now, I finally know where the dog was buried so to say, I guess to really fix this id need an update for that can bus-app, which probably Xtrons won't provide
I hope this helped everyone else with that problem, and I'd appreciate any ideas on how to proceed with that can bus-app
have a good one,
Hello, today is your lucky day
I have a 2010 audi ttrs and a Xtron TE706PL with Rom Hal9K ... and i have can bus original from Xtron.

For the problem of the amp remaining simply connect the cable vag com and select "1 via remote wire", which will tin the amp with the +15 contact.
For the problem of noise parasite, just go down, with the vag com, the level of the amp, but you can if you want raise the level of the Xtron radio, I'm at -6db for the amp bose.

Hello,
By changing this option, the original bose amplifier will shut off when you turn off and take off the car key.
