I have seen many posts about the new update that has come across most of people's trucks that have the 12" screen, but I have been wondering, as someone coming from a 8" UC4 (12" UC5 now), will I ever get an update past what was on the device before I bought it? If not, is there a way to get that firmware from outside of the dealership, and would they even give me the upgrade if I asked for it?
