Now it's my turn...
On the '97 I just picked up, the PO installed a BMW Business CD player. He wrote the code on the inside of the owner's manual as well as on the unit itself. The problem is that the code he wrote is a four digit number when the unit is asking for a five digit number. The shop here called BMW for the code, based on the S/N of the head unit (the VIN wont work, since the unit is not native to the car it is installed in) and got a five digit code. This still does not work. They've been trying for about a half day now to get the code input correctly and have so far been unsuccessful. Not sure what to do now... anyone have any suggestions?
UPDATE- (and this just sounds as ridiculously crazy as it does believable) So apparently the four digit codes are Euro codes and the five digit codes are USA codes. To enter a Euro code, you have to put the unit into service mode, change the area code from USA --> Euro, enter the four digit code to unlock the unit, go back into service mode to change the area code back Euro --> USA, problem solved.
