Regarding the "Trailer Hitch Cam". When I took possession of my 2016 Big Horn, there was a "CAMERA" icon already ready present in the APPS folder. I dragged it to the task bar in place of the "MEDIA" icon, and I can activate the rear camera at any time. It closes out after a time. I've got no other listing for a specific trailer hitch cam, but it seems I have no need to do anything.
Would that camera icon appear on the SRT Themed Controls pages??
(I really don't understand fully what these "pages" are, or if changing themes is strictly cosmetic, or it controls and functions are added. My old Tundra had a dashboard and a radio with dials!! Just sayin'...)
