I have enjoyed reading the conversations about the backup sensors. I am the owner of a 2023 GMC SLT Sierra 1500. My vehicle does not have the back up sensors and I was wondering if there were some kind of place where I could have some sensors put on my rear bumper, but after reading all these comments and it makes sense that it would have to be programmed and all this and that so I’m kind of getting disappointed . it seems that it would be too much trouble to have it done ,if possible and very expensive if you had it done at a GM dealership ,they would probably charge you a whole lot. I just wish my 2023 GMC Sierra had come with these back up sensors and front sensors also .just wondering if it can be done correctly and at a fairly reasonable cost?
