Bose 6 disc vs. Navigation

[SkiUtah]

Does anyone know if the Bose 6 disc and the factory gm navigation radio have the same plugs on the rear of the radio? My few concerns are: Is it plug and play? Will the steering wheel controls work? Is there any other mods that need to be done to make the nav work ie. antenna or control module? Does the radio have the XM module in it or will I have to buy something extra? I have one i can get for really cheap that has never been installed and want to make sure it will work before I get it.

Thanks in advance.
