I have the pioneer optional 12 disc changer and tape head unit (factory fit) in my '96 320i touring. The changer is plugged in at both ends and earthed but nothing lights up and it doesn't seem to work. I.E. the cassette that holds the discs doesn't eject when the button is pushed. Recently bought the car. Any ideas? Is this a common fault. Do I need a new changer?
Cheers for any help.
