I have the RES with sat radio and optional uconnect but i dont have the uconnect in the truck, if I purchase a Ram touchscreen without nav does it hook right up with my existing wiring? Do I have to have it programmed for my truck or something? My buddy changed his in his truck and I was gonna buy it if it was plug n play or close to it. His truck is a 2009 and radio is an REZ i think.
