haven't found the solution yet. Just happened a couple of weeks ago when I moved the changer from the stock location and put it in the glove box. I'm using a factory BMW cable and have it installed the same way. I'm assuming it has something to do with programming because I've checked all of the connections. I will update when i find a solution. I'm pretty good with the radio's in these...Also, are you having any problems with the in dash cd? I think my problems may be connected as my in dash cd has recently had problems reading disc's. It will read them start playing, go staticy and then report a cd error.
