Sorry to revive a dead topic here, I am trying to figure out how to get this to work on my truck. I have a 2020 LTZ, which from the ordering guides I have looked at, has the U1D package. I don't believe that the PTT was optioned on this truck. I have requested a build sheet to confirm the options. I took off my rear license plate and it has the Schrader box that mounted in the photo above. From the research I've done, it seems like thats the transmit box. When I setup my trailer, it never gave me an option to monitor for tire pressure. Do you need to have the sensors in range for it to show up as an option in the onscreen trailering app? I don't want to order a set of sensors if its never going to work on my truck.
Appreciate the help!
