I have an 04 Escalade with a CD changer. The one mounted next to the clock above the ashtray. It wont allow any CDs to be inserted. And yes it is completely empty. None of the button lights are lit. If you push the eject and load buttons it does make a click sound so it apparently is getting power. Anyone else have this problem? Guess I need to fine a stereo repair shop. I dread that!
