CD Player problem
I have a problem with my newly purchased '94 318i. My old '92 318i didn't have an amp, this new one does.
Here is the problem, I have a SONY cd head unit which I just got. The CD-player doesn't work on the car, only the radio. I mean there is no sound when the CD is playing, and there is sound on radio mode. The guy at the shop tested it and said the head unit is working properly, and it was. He said something about a blue wire hooked up to the amp that I have to connect? I'm not sure what to do exactly.. is there something I have to connect on the wiring harness? Or is there something I have to bypass or cut? The audio store guy says the SONY head unit has some security feature which prevents the CD audio from being heard when an amp or speaker is not connected (all speakers are working)...
