I have a CDR-23 in good cosmetic and excellent working condition and the matching amp from my 2004 Boxster. I removed both to install a double DIN unit. They are MOST units so the radio does not have a code but would need to be synced with your car using the Porsche software available at the dealer or an indy. I'm flexible on price as they will otherwise sit in my basement. I'm asking $75 for the amp and/or $100 for the radio. Make an offer. you pay shipping. Sorry for the GIANT images. Didn't realize they were so huge and now don't see how to fix them.
