a while back my CD player quit working. It's a 6 disc in dash changer with satellite radio. All other parts of the radio seem to work fine. but it just won't even switch to CD player when you press the mode button. The weird part is that every time I open the drivers door, I can hear the CD changer trying to do something. And every so often I hear the CD player trying to make some sort of noise. I kind of wonder if it's stuck trying to eject a CD. Any thoughts?
