A fix was found for AA not starting. I'm not going to get into what was causing the problem until it has been tested. Please post in gitter your results.

I've also removed the automatic sm.conf install, as people can't be bothered to read for 30 minutes before installing this sketchy code on their 20k car... Look at old releases and patch manually if you want automatic audio and buttons.

Issues have been encountered with new versions of google play services. If you have a fully up to date phone, it probably won't let you use AA.

Only tested on v55. If you are on another version, I suggest removing the sm.conf from the zip file. As that file has a tendency to change with each release and is critical to CMU function.

See for more details.

Slight update, working towards a permanent audio fix.


  • When using fav key to switch to radio, track keys allow you to change between presets
  • When exiting AA, audio automatically switches back to radio

Slight update to hopefully fix some of the not_running errors. Should be safer for v56 too.

An uninstaller is also attached.

NO WARRANTY IMPLIED. Some of the things I/we do to get things to work are super sketchy. Use extreme caution if you've messed with any of the car's file system or installed lots of mods. Please report bugs in the issue tracker. If you report a bug, I expect that you'll have SSH access to the system to debug things. Note, there's only so much progress that can be made without knowing the full android auto spec.

Install procedure

  1. Read the OP
  2. Read the OP again
  3. Skim the thread quick to see some common issues
  4. Copy (extract) zip file onto blank USB drive (FAT < 8GB)
  5. Start car
  6. After car has started, insert usb drive
  7. Wait until prompts pop up (can be up to 5 minutes)
  8. Follow prompts, and the install should be complete.


  1. Start Car
  2. Wait until infotainment system is fully booted (Android Auto menu option not gray)
  3. Plug phone in
  4. Select Android Auto option

If you want to be able to connect your phone at any stage, you should alway keep a usb drive with media in the car. It don't have to be playing, just connected. I didn't confirm this advice.

If audio doesn't work, unplug the phone and reboot the car (hold back + nav + mute)
