Hello everyone just want to say thx for the help from all the threads that helped with questions I always need answers for. I'm new to signing up but not new to the family. I have a question that I can't find anyone else that had the and issue. I have a 07 yukon denali xl. I want to upgrade the factory flip down with an aftermarket one but I want to keep the factory navi. I still want to control the DVD function from up front. Kids are all still young. Don't want them touching anything but headphones. I was told 2 different answers. 1 shop said it can't be done. Only with fords can you tap I to a factory harness. Another shop said it can be done if the experienced tech does it. I told myself who would really know. And all of you popped up in my mind and I surprised not to see the same question from anyone else. So if someone can help me please don't hesitate. Also any good brand suggestions. I was thing about the 22" T-View I see mixed reviews about them anyone with some experience. Thx in advanced.
