Android auto / carplay media interface all done, 2G mmi not very plug n play, need to wire into fuse box 12v,12acc, ground, 2 orange wires to candus +- wire to the pin 16 of mmi power plug for NAV button to switch between factory mmi & carplay on screen,
Fitted the mic up in the spare hole in roof light for ok Google /siri. Audio out to ami-3.5mm aux, also ran a usb extension lead to the armrest, but can use for a usb drive as found it had wifi & both carplay & auto work wireless.
Unlike a factory AA CP will play video & stream with mirror cast from phone, have a few hacked apps to try too.
Add a new level to a tired 2007 2G A5.
