The factory backup camera on my 2014 Chrysler minivan (mounted above the rear licenses plate) is superb. The unit on my wife's 2016 Volvo is even better. I will not buy a future vehicle without one.
I'll try to buy one for my 54/55 GMC COE. The "display" will probably be a GPS display. I do not know enough to choose between wi-fi or fiber-option lead/connection. These after-market units might not yet be ready for "prime time" - I'll try to learn from on-line reviews (and from members here who have recent first-hand experiences).
