It depends on who you talk to at the dealer.
Had mine installed last winter at the dealer. The first thing I did was check to see it they were in the UConnect system, they were not. I ask why and no one had any idea what I was talking about. I told them the whole reason I had the install them was so the sales code could be added to my truck for warranty reasons and so the steps could be deployed/stowed through UConnect. This was a Saturday so they asked if I could bring the truck back on Monday when another tech was available. Brought it back that Monday talked to the tech, he knew exactly want I wanted, and had everything working a short time. So yes, it can be added to the UConnect at the dealer.
