Does anyone know if you can hook-up another back-up camera to the Z1 besides the ND-BC1? I have a 2005 Lariat SCREW and I do not see a good place to mount the ND-BC1. I was thinking about getting a license plate or 3rd brake light camera. Any inputs?

You should be able to use any camera with a RCA output I would think...

you can, you just need an RCA output camera, that powers its self.
