I'm replacing my command system (w164 2009) with an updated android head unit - does anyone have a wiring diagram of the command unit? Mostly I'm curious on the different colored cables (GPS, ANT, MIC, etc) so that I have each routed to the correct place.

Also, the new head unit seems to get terrible radio reception (assuming I have the correct cable going into the HU (white with purple?)... is there anything odd/different about what the command unit expected or what the antenna sent?


Thanks!

Which radio did you get? And what year vehicle? I am currently in the same boat as far as reception goes. I still have not figured out which oem wires are for the steering wheel controls. Back to the reception. I think the problem is the antenna adapter that was provided. I believe we need one with a built in relay.
