That’s just how the truck is wired with that option. From the brochure above: “vehicle built with surround view option are prepped for mopar trailer 360 offering”.Limited level 1 includes regular surround. Ok good there is a 12 pin. How many aux cams can I add then (since there is no xn1 to occupy aux 1)? Or are you saying that regular surround DOES occupy aux 1 because regular surround PREPS for trailer surround?
What is the purpose of the 12 pin when regular surround is configured (why does regular surround = 12 pin)? Is this the prep for trailer surround and the aux 2 cam?
Since it has surround view, you can add only 1 aux trailer camera. This is because when the BCM is configured for surround view, when you activate the aux trailer setting in the BCM, the radio will populate the trailer surround view and aux2 camera soft keys in the more cameras menu.
