6.2 Position Page
The Position Page shows your location, what direc-
tion you're heading, and how fast you're going, and it' s
most useful when you are traveling without an active
destination waypoint. The graphic heading display at
the top of the page indicates the direction you're head-
ing, or track (only while you're moving).
Directly below this display are the speed, average
speed, trip timer, trip odometer and sunrise/sunset
fields (default). The sunrise/sunset times indicated are
for your present position. These times, and the current
time display at the bottom of the page, can be dis-
played in local or UTC (universal) time. The lower left-
hand corner of the page shows your current latitude
and longitude in degrees and minutes (default).
