I purchased my 740il in '97 and lately have problems with the cd-changer skipping over relatively small bumps. I'm out of warranty...took it to dealer and they suggested new magazine which did not fix problem. Any suggestions on whether to suck it up and buy new cd-changer from dealer or to get one from a local car stereo dealer? If latter, what should I get that will work with the BMW stereo (premium sound) system?
