I have a 2000 M5, and it is equipped with a radio cassette and a cd changer. I want to install an aftermarket receiver with mp3 capability, and I want to send it's signal directly to the amplifier, so I need to know which wires on the ampli are the sound inputs. Do someone knows it?
The ampli model is "BMW 65.12-6 905 119". Ther is 3 plugs on it, with many wires each.
I guess I can intercept left +/- and right +/- inputs only and the ampli will receive the good signal. But will this create a conflit if the old components remain connected. I wont use them anyway, I could disconnect them for good. So I would only need to leave the ground and 12V inputs...
Anyway, if someone has the full wiring diagram, I would be very thankful!
