Have an 95 E36 M3. It has the factory radio with a Pioneer 6 disc CD changer in the trunk. Was working fine ever sine I got the car until last week.

Normally when you press the PROG button on the headunit it switches from FM to AM to CD. But When I press it now I dont get my CD feature. I checked the CD changer to make sure noting was wrong with that. Dics go in and come out fine. It does have power and seems fine.

Could there be a problem with my head unit?? Or something else. Please help out if you can. Thanks
