I only assume the missing 4 updates are mostly navigation related. The 1.2.1 was insufficient in Navigation search. I couldn’t use navigation to find EA charging stations. It was embarrassment to show my wife and brother that I couldn’t find complimentary fast chargers from navigation when needed. My brother lectured “What’s point of free fast charging if they don’t want you to find them? That’s what you get for not listening to me to get Tesla instead.”
Anyway, I told them it will get better. And this version (2 months) it is some milestone. Navigation now shows each step, freeway exit has number instead of road name, it even plans and shows where to detour for charging station for long distance drive, also can click on many zoomed location to get business details, ratings and phone number. Click on phone number, it auto blue tooth call. I don’t need to drive and play with phone at same time. When I drive my Jeep Wrangler, I cannot manage that small 6 inches CarPlay screen, I have to pick up iPhone to search information. Here the dual screens can cover more places to click and search instead.
