I checked my manual and it's much less informative. Looking at my settings on MyTouch, it shows display options (time, date or off), format (12 or 24 hour clock) and an option for daylight savings time. No GPS. Wondering if the GPS function is only part of the nav system, which I do not have. <??>
I set mine to use daylight savings time, since it wasn't, and see what that does. It seems to set the calendar automatically and knew it was today's date, it does not however show a year.
