Went to the dealer today, with the radio out. On the bottom it has a sticker with the following numbers:
A003 8205 186
stamped in metal S/N AL 2294 R 10 46650
According to the service guy, he pulled the code based on the sticker number. He gave me 31122. Entered the code following manual directions (press SC after code entered), tried a couple of times until it locked.
Called again the dealer, and the same guy told me that nothing comes up for the S/N stamped in the bottom.
The radio is not original to the VIN
