What are you replacing it with? Factory or after market? Radio and cd/changer are separate units. Radio or changer can quit working separately BUT changer will not work without the radio. Radio must be working to checkout the changer.. As far as changing them with factory, is very simple. Post to let us know why you are replacing them. Upon knowing, we can tell you how to go about it.
Looking at the pioneer cg-c8303u from crutchfield, but, the modifications that are needed, they can't help with. The original factory radio lost it's display and it shuts down ocassionally.
