I bought a C300 last month and I love the car!. My only complaint is.... the firmware on the media console does not allow you to copy your MP3 to the 4gig partition which pisses me off. The console has 30gig but they partition 26gig for the NAV system which is insane but on the remaining 4gig they only allow you to rip CD's directly and prevent you from copying MP3s which is so lame.

Does anyone know how to get to the backdoor/service menu or know how to transfer MP3's to the 4gig partition on HD?
