2008+ USB/Aux factory wiring
Hey all, does anyone know where (big connector behind the radio) the USB/Aux wiring goes to? Maybe a wiring diagram? My 2008 has the USB and Aux 3.5mm ports in the armrest compartment - I'd like to find the other end.
The big plug has the 12-pin connector for what I thought was the Aux input, but it only has 3 wires in it. So confused...
2008 M5 6MT, purchased with 55,200 miles on her
