Hello I have a 2002 X5 3.0i, it has the "business cd" stereo with the amp & subs and x # of speakers. Pixels are out so I want to install an Alpine HU and I got the harness but all it does is power on, no sound. It appears that the speaker wires do not match up between the factory harness and the install harness. Also, I noticed that there is no am/fm reception.
Is it possible to utilize the factory amp and antenna (I used an adaptor wire but still no reception)?
Is there a way to communicate with the factory amp using factory wiring and Alpine HU (without having to run cables all the way back)?
