I've had my E220 CDI for 3 weeks (6 months old), and had regular problems with the 6 CD changer in it. However, now the bloody thing just sits there with 'track' and nothing happens and I can't eject any CD's. The radio and single CD both work fine. Also anyone got a cheap 6310i for sale, as I've got the full wired up system in the new car and no phone.
