If you're one that needs to use Aux In, then you're familiar with the poor quality (again subjective, much less than OEM INDIVIDUAL) of sound output by the Android Monitor, at least certain versions.
Any idea which cars / bmw packages work without needing the aux?
@Bilbofraggins IF you don't need aux in for your install, please take a pic of your radio connector so we can see what pins you have to compare to ours that don't. Maybe we can tie it to something....

Also image of socket on the back of the radio (aka: car info computer)...

A theory...I can see the possibility of those with rear entertainment system not needing AUX IN. I checked out the wiring schematics and there are two types of AUX INPUT in our BMWs, each located in the same spot, center armrest. One AUX IN without Rear Seat Entertainment (RSE) option is 3 or 4-pin and is wired directly into the Car Information Computer (radio) in the dash. Another AUX IN with RSE option is 6-pin where 3 pins are wired to the Car Information Computer and 3 pins are wired to the RSE DVD. From there, the RSE DVD player connects to a headset connection module in the trunk where all the other SSP options (satellite, hud, ulf, cd/dvd changer, tuner, etc) arrive and are connected back to the Car Information Computer via optical cables. Which I believe means (since I've never had that option) you can pipe the DVD Rear Audio through the Car Info Computer and then OEM Speakers. FWIW.
