Just to keep the thread going, here's a pic of how the LEDS and Android unit match audi leds:
i still havent hooked up the reverse cam as the cable was short by about 1m and had to get another lenght of RCA cable and a coupler.
One issue i found so far is that when you turn the volume all the way down to zero and then more than 0 you will hear a loud pop in the speakers, same when you start the car up you will hear a loud pop i think this is because of having the bose amplifier so I will also have to have a think how to address it.
The video is coming I just have to get the reverse cam working and a few other things
