the + sign is to zoom in reverse.

 

OP, my overall point is if you hit the camera button on the dash piece when in reverse, does that split view go away?

 

It most likely will, but OP is asking how to change the default screen so that button press is not required.

AFAIK it is not possible and it will always start in the 360 view. (Unless maybe disabling the 360 cameras in forscan, not ideal)

 

Yes. If I push the + (zoom) key it displays the camera full screen. Seems like it should be a software setting somewhere. I don't think my truck is behaving abnormally.

 

In a related problem, after 3 1/2 years my zoom function stopped working. The regular back up camera works fine. When I push the plus sign, it changes states but no zoom appears. Any ideas?
