Bob,
Not sure what else you would like to know, as I said it is a 10 inch monitor and can be configured for 1, 2 , 3, or 4 screens. However it is configured it jumps to the needed screen when triggered. Basic configurations such as 1,2,or 4 are on buttons. Three screen configurations or moving screen around are through a menu. I had an issue that it would not stay on a selected screen at first, and rear View safety was great about replacing it immediately.
You do have to be aware that resolution is less because of the larger screen, particularly noticeable when bright sun is behind you. It comes with everything you need for surface or pedestal mount.
I used it on a 4000 mile trip and particularly in city traffic I love it.
I am hoping I can figure out how to plug GPS into the fourth screen.
