I'm going crazy here... I bought a super clean 88 Porsche 944s but it had some dumb looking aftermarket Blaupunkt stereo in it. Thankfuly, the seller gave me a nearly new Becker CDR 210 from a later 911 to put in the car. The radio has a "993" part number.
Of course I didn't get the security code.
The serial number is 2282E00W5023484
Please help! the stero looks great but no sound is a bit of a drag.
