SETTING THE CLOCK
1. Press the Settings icon > Clock.
2. Press + and — to adjust the time.
From this screen, you can also access other adjustments such as 12 or
24 hour mode, to activate GPS time synchronization, and to have the
system automatically update new time zones.
Once you update any settings they will be automatically saved.
Note: The date will be set by your vehicle’s GPS. You cannot manually
set the date.
Note: After a battery disconnect, your vehicle will need to acquire a GPS
signal to update the clock. A GPS signal can be received in an open sky
area. Once your vehicle acquires the signal, it may take a few minutes
for the update to display the correct time.
