Hi just fixed my cd changer that hasn't worked since I had the car. The fault was a stuck cd in the cassette which must have made the fuse blow at the rear of the unit. An absolute pig of a job which included taking out the centre console to get access to it then taking the changer to bits to get the offending cd back into the cassette then powering back up and ejecting it. All is working perfect now. I know I should have taken some pics but didn't think about it until it was all back together. There is a you tube video that was very helpful where they are showing you how to change the sat Nav drive and how to take the centre console out, although they did miss quite a few screws out on the video. A very bad design idea from BMW making it so hard to access because I imagine it will be only a matter of time before a CD gets jammed again.
