I work for a GMC dealership. It has been a frustrating experience for me with no help from GM. If it is further than 23' to any of the tires on your trailer from your back bumper, I don't know if I would waste the money like I did having the sensors installed., They will work but keep dropping signal. When they drop signal you get an error message on the dash you have to keep dismissing. If someone comes up with a compatible repeater I'm sure it will solve this issue. My aftermarket TST system worked fine. I had a 2019 before the 2020 and one of the main reasons I stepped up to a 2020 was the improved technology features which in my opinion were misrepresented by General Motors.
