Escalade radio help

There are several conditions with this radio that can occur, to many specifics to list. It doesn't list how many miles you have on your vehicle, but if it is still warrantible, I would recommend taking it in. They developed a disc to upgrade the SuperNav radio that your vehicle is equipped with, and it may correct your concerns if the reboot mentioned earlier provides no success.

Does it do anything like load, or unload. Often times if there is an issue with the changer, it either needs to be removed and sent in for service, or replaced.
