Question is, how does one activate GPS time synchronization and outside air temp display on plain-vanilla SEL? Are these Nav-only functions? On page 478 of my owners manual (My Ford Touch -> Settings -> Clock) it says: From this screen, you can also make other adjustments, such as 12– or24–hour mode, activate GPS time synchronization and have the systemautomatically update for daylight savings time and new time zones. You can also turn the outside air temperature display on and off. Whenthe outside air temperature is displayed, it appears at the top center ofthe touchscreen next to the time and date.
