This happened in my dads bmw while he was away. My mum took it up to the dealership and they said it would cost a few hundred bucks as they had to send it off to a specialist audio company ouich, so mum decided to wait till my dad got home and talk to him about it. When he got home he got a fork and five minutes later it was all fixed, the cd had just slightly dislodged and was blocking it from ejecting.:applause:
