Iam just trying to figure and plan everything out before I go.
I hooked it up roughly again just to try the GPS antenna. Signal seems to be strong, I shoved in the dash just to see and it had good signal, so that's where I'll be putting the GPS antenna behind the unit in the dash . The other question I have is where do I hook up the orange Ilumini wire to? So that the lights on the new unit work.

Also the camera I got is supposed to fit in the license plate light, but that's the upper part of the trunk and no way to connect to a reverse wire from there. The reverse light is on the bottom hatch. Does that mean I have to get the round one and drill it in that area?
