Upgrade to factory Navigation
I have an 03 Deville with the base radio and On-Star. I want to install the factory navigation radio. Is this possible by just installing the navigation head? Will I also need a processor, or just a cable to link the Onstar Nav to the navigation head? What enabling the XM radio in the navigation head? Help.
