becker cdr 220 radio code

[kyleengman]

Can anyone help with the code for my 02 Boxster s? under the hood it has a handwritten 4 digit number that has been crossed out with a 5 digit number. I've tried both the 4 digit and the first 4 numbers of the 5 digit without success. serial number is 25015469. Love the car, but can't understand all the hoopla around the radio. It certainly isn't that valuable.
