My friend has a Durango with the same stereo that comes in the Caliber: AM/FM/CD/MP3 w/6 disc changer. He inserted a CD and everything just jammed up on him. It won't change discs and it won't play discs. He can't get anything to eject. Basically, his unit is AM/FM only at this point. He thinks that if he can get into the unit and remove whatever disc is jamming things up, he can get it working again. He can get the unit out of the dash, but he doesn't know what to do from there. Any suggestions for him? Anyone have experience opening up these units?
