I'm certain they're completely different. Best you could do is get the camera that works with the truck and figure out how to adapt it to whatever mount is already there.
I'd like a furrion receiver that doesn't have a screen, but instead an auxiliary output. Then wire that in to the onboard screen.
Though, I now put the furrion on my rear view mirror, which is really natural.
