I've got a 2016 A4 that I'm trying to use with CarPlay and my iPhone X via USB connection. It works most of the time, but occasionally I get random bugs:
- Phone seems to connect (shows CarPlay screen) but MMI shows that there is no compatible device connected.
- Phone seems to connect and MMI screen shows the CarPlay controls for audio, but when you play audio it comes out of the phone speakers not the car.
