cd stuck in radio
 

I don't know how to remove a disk that is stuck in the cd loader.

I was listening to disk 3 and then suddenly the music stopped and the display was showing cd 3 error. I shut off the radio and now it is always showing cd loading and nothing happen.

what could I do to fix this or if I need, How to remove the radio from there.

2006 a4 with 6cd loader

thanks a lot
