Hi guys, I have a 2002 530i with the 16/9 NAV and need help finding the wiring diagram for the radio module in the trunk.

Essentially, it looks like I need to troubleshoot a short in the trunk and need to know the which cables are for power and accessory for the radio.

I believe the radio is a BM53, but I can't find the wiring diagram for it... Any help will be very welcome!
