Using the manual, I went through the menus and changed settings so GPS sets the exact time and accounts for daylight savings, but no where did I find any way to have that time display on the 11 inch screen. So what is the point of the unit having the timekeeping if its not used anywhere other than to say charging to be done by day and time. Just surprised that the GPS time wasn't displayed anywhere on the screen. Guess that's just the way software was designed. And now I am out of luck for map updates for my 2018 Prime. Luckily I bought the latest Garmin as we are finding some of the road interchanges are getting out of date.
