I forgot the raio code for my 2001 boxster. after installing a new battery recently, i must key in the 4 digit radio code to get the stereo to work.

I found a number preceeded by an R written on a label on the insdie of the hood [it was hand written by the previous owner or the dealer, I'm not sure]. The label also contained the engine code, the paint number, and a few other numbers. Anyway, I tried the number and it worked!
