I just got a 2003 AV Z71 all stock radio last week. I want to add a new HU with Navi and rear view.
I know I will need to find the unit I want but what connectors will I need to keep my steering wheel controls as well as Bose and OnStar working. I have searched and I have found 3 different harnesses but some say they do it all but reviews say otherwise.
I found this site doing a search for this info and it seems you guys would know quicker than anyone else. Any help is appreciated.
