I have an original Bose 1998 A4 system that stopped working. I checked all teh fuses and all seem to be ok. Is there a fuse on the radio itself? I hear that there is one but to get to it I have to take the radio out... Can somebody tell me how to get it out? Do I need a special tool?

 

yes there should be a fuse on the back of the radio. You'll need special keys to remove your radio.
