I'm trying to find out if anyone has been able to add the Curb View/Assist function to their truck. I have mirrors on my truck from an SS, so if the mirror itself is any different that's covered. I have an LT with all the options but the Bose system and the convenience package (what includes the heated/memory seats and related functions). The door modules are what control the memory functions. Unlike a Tahoe which I can go a reprogram the door module and choose which mirrors it is equipped with and add the functionality, I cannot do so on these trucks. I just tried reprogramming both door modules (as well as I updated all the calibrations for every other module in the truck), and I am unable to add this function. Right now all I can think of is that I need to buy door modules that are for trucks with heated seats. Does anyone else have any insight into this or will I be the first?
