I am getting the 801a package and it does not include: Remote door opener? Do I have to use a key to get in? Garage Door Opener? Can I add it later? Just buy the unit? Not sure on the tailgate opening? Do I get it or not? I know I get no FOB, so what else is on the FOB that I might miss? Does the Apple carplay work across Sync 3? I just want to put up my own maps on the 8 inch display. Is there a way to track my build? I do not have the VIN yet.
