325 radio code??

Just bought a 1992 325ic.....which came with a 5-digit radio code, but I cannot get it to work. No manual. What is the procedure for unlocking the radio? Any help is appreciated..........

I have no manual for my '86 325 either, so I took it to a BMW dealer in my area and they removed the radio, got the serial #, and looked it up on their computer. The charge was $13 (US) but you'll have the code for whenever you have to disconnect the battery, which will reset the anti-theft feature and lock-out your radio once again.
