i am looking for the radio/antenna wiring diagram for a 82 633CSI to trouble shoot radio. I found wiring diagram for 83 633CSI, which appears to be very different. Radio and Antenna stopped working,... I checked the fuse which is fine,.. is there another fuse panel somewhere that I need to check? Any help would be appreciated. Alan
There's a couple of '82 etm's here - a look at those, if they have radio wiring diagrams, you'll probably be able to see if they're applicable for you - http://wedophones.com/BMWManualsLead.htm I wonder if that head unit might have it's own fuse...
