Changers on the XLR are one of the first things to go belly up. Mine was broke when I bought the car. I tried on Ebay and actually got a whole new/used head unit for a reasonable price. When I got it, the changer wouldn't work on that one either. Fortunately I was able to get my money back. I went on for several months and bit the bullet for an upgrade to a new Kenwood unit. Now the car has a pretty much state of the art head unit including Android Auto/Apple Car Play. Before you pop out 1100$ or more on another changer that can go out at any time, consider what i did.
