Forgive me if I totally don't understand this, but it is my understanding that the software run on the screens is uconnect and has different versions, where 4 is on a lot of vehicles now and 5 is just coming out. Is that correct, or is it specific to the type of screen you have? If that is the case, are these just a software upgrade or is it screen specific? The cool thing that stood out when reading about uconnect 5 was the wireless Android Auto so just wondering if you get a brand new truck that still has 4 on it, if it is upgradeable.
