I posted previous progress repair about this on someone else's post about a year and half ago, now i do not see the post on any search. It was in response to an owner who had CDR 24 radio stopped working, or was erratic and they replaced it and wala! found out like me that the CDR 24 (once it is replaced with a foreign unit) has an engineered no radio code in order to boot it back up. There were numerous posts about CDR 24 problems, now today i do not see any! I wonder what happened here.
Anyway he was directed to go to Porsche dealer to have the new radio programmed to his Boxter and
