Distance and Sun Calculations
The distance and sun calculation page will give you
the distance and bearing between any two waypoints or
between your present position and a waypoint. It will
also calculate the sunrise and sunset (in local time) for a
particular date at either your present position or any
stored waypoint.
To perform a distance and sun calculation:

and press
E
.
2. Highlight the ‘TO’ field, enter the destination waypoint,
and press

.
3. The ‘DATE’ field will become highlighted. Enter the
date you’ll arrive at your destination, and press

If you haven’t marked your present position as a
waypoint or you leave the ‘TO’ field blank, the sunrise
and sunset at your present position will be shown.
