This might be confusing and maybe someone else can explain more simply....
There is a "surround view camera system" that is just for the truck. It stitches together cameras on the front grille, the side mirrors, and the rear. If you have this system on your window sticker, or in the build sheet, it should work. Uconnect should show different camera views on the center screen, as well as a top-down view of all cameras together.
The cameras that can be added to a trailer are a completely different subject, and the subject of this thread. There are three versions of this, which are described in this thread and others: 1. Aux1 & Aux2 (displayed in center Uconnect screen), 2. Trailer surround system (also displayed in Uconnect center screen), and 3. A single remote trailer camera that will display in the digital rear view mirror. Due to the new electrical architecture of the 2025, these don't seem to be working as they did in the prior models.
I think you're asking about the surround view on just the truck, but if you're asking something else, maybe this info can help you narrow down your question. We'll help if we can!
