I am considering buying a 2007 Tahoe LTZ, it has the rear DVD that drops down from the ceiling. The HU doesn't have any screen or anything. If I buy the truck, I want to be able install a touchscreen DVD, Nav unit. So the question is, if it swap out the HU, will I retain the functionality of the rear DVD or will I need to install something else, possible screens in the headrests or something.
Thanks for any help!
