well folks, I've been trying to get the code for the factory radio for my 2000 Volvo S40. The dealership was willing to share the code but it didn't work so I'm forced to try and get the code from the serial numbers. They read V 08170 W1229151 B. Serial # 3533771-1. There's also a line of numbers reading 4980 9801. Any advice or help would be greatly appreciated.
