I took what 8ball posted to my Dealer in Pensacola, FL and the tech was able to update mine on a 2022 so it can be done, as others have posted, finding the right Dealer, and bye the way he submitted the work and was paid by GM. I have a working relationship with the tech and tip him for his work. Always takes care of my truck. Several small issues handled by him.
