I finished 8.4 non nav to 12” upgrade. All works great. I would like to use the guardian services. How ever they won’t let me activate even when trying to use original truck VIN as the want proof of purchase for that truck of some sort. I was told if radio was put in as factory to my truck this would take care of that issue. I have called 3 dealerships and called FCA for help and no one really knows. Anyone able to get that done? If so how did you get it done? Thanks In advance.
