question.

going to install a camera on my truck, but also going to install one on the back of my travel trailer going into the av1 input on the rear of the d3.

so when I put my truck in reverse, the truck cam will come on, can I view the av1 input cam on the trailer by selecting av1 or will the reverse truck cam over ride the av1 image?

i believe the reverse input will overide any other source when the car is put into reverse. but you can go into the settings menu and temporarily shut the camers input off whenever needed
