becker cdr 220 radio code

[Novas1but74]

Hello all. Am new to the forum. Relatively recently acquired a 2001 986 S. Have been working on getting it road worthy again as past owner left it sitting in his garage for past 3 years. Looking for the radio code for the cdr 220 radio. There is no book with car and not hand written on underside of the frunk and the serial number under the hood is YU663209. Any help would be much appreciated!
