:bonkers:Just purchased a 2004 Escalade and it doesn't have factory DVD or Navigation. It does have the Y91 option with Bose. I see many of the same factory navigation and dvd system parts on ebay. What we would like to do is intall the newer touch screen navigation system (that was in '05 & '06 Escalades) as well as the same Panasonic drop down DVD player that was installed from the factory. Is the wiring system already in place in our vehicle for these two systems? Is the mounting hardware for the DVD player in the vehicle? Are they hard to install? ANY HELP anyone has would be greatly appreciated, and if there are any GM techs who do this for a living for a dealership in the Chicagoland are looking for a side job please contact us. Thanks you, Thank you, Thank you!!:bonkers: Forgot to ask; if we decide to go with the two headrest DVD players is that easy or easier to do than the drop down units?? Thanks again!
