For what it's worth, 40% of the time I access the volvo database for a radio code by VIN #, it's wrong cause the radio got replaced and the database did not get updated. At this point, you slip it out of the dash aand do a search by serial #. Up pops the code, car on it's way. So nall you gotta do is install the radio, go to a dealer, tell em you lost the code, and they will usually get it.
