Is this what I need to add backup camera?

[OrangeCrush]

Thanks guys but one question. I plan on adding two cameras (possibly a 3rd like I did on my enclosed trailer on my older H2)

If I'm bouncing from camera to camera, is that what I need a video switcher for? Is a video switcher used to go from one video source to another?

Most of the integration packages for the OEM nav allow two video sources... How would you switch from one video source to another?

Thanks,

Mark
