We are releasing a patch that prevents the head unit from taking over the audio from the phone. It will allow you to keep the Bluetooth (or whatever normal audio path) you have :) That also means the Pi needs to do less too, which means it will not jank.

Oh, very nice! So I can have the two together, you mean, side by side?

  It means that you can use the Pi as just a display (instead of as a display and an amp at the same time). Normally, when you plug the phone into the Pi, the phone won't play audio anymore. Instead, it asks the Pi to play the audio for it. Normally, that's a good assumption because it's connected to a dedicated head unit that has an amp. Now with this DIY RPi thing, we broke that assumption: the Pi has a bad DAC and doesn't have audio input (and the performance is janky now at times for unknown reasons). I was just tipped by Emil, another developer who got really deep into hacking this. He told me that there are ways for the Pi to say "I'm not interested in helping you project the audio, you just keep playing whatever you normally play." So now your phone only projects the UI/maps to the Pi, but still routes audio/Hands-free directly to your stereo through BT. A benefit of that is you can use your handsfree, buttons/controls built into your steering wheels fine if your car has native Bluetooth. That workaround has some problems with Chinese phones we realized, but works OK for a couple of Nexus/Pixel we tested.

    Oh, that's amazing! I'm going to look into getting the kit and setting this up, thank you for all your work. My phone is a Xiaomi, so I don't know if it's going to have problems, but being able to navigate on a front-mounted display would be fantastic. I guess I can just test it with my TV first, thanks again! EDIT: Can you write some installation instructions somewhere prominently? I know I probably just need to burn the image to an SD card, but many others won't. I recommend https://etcher.io/ https://etcher.io/, if you want to mention some piece of software, as that works quite well.

      Yep, thanks! The installation instructions is in the works. I might need to remove the "no manual needed" part :)

    I wonder if you'll also see the same audio routing problems on Samsungs (S8?) as they do some custom audio stuff to support multiple bluetooth devices / multiple outputs.
