to move the cursor to the reference field.
6. Press
E
to begin entry of the reference waypoint.
7. Use the arrow keypad to enter the waypoint name.
8. Press the
E
key to confirm your entry.

the reference waypoint. Remember to use the

The GPS 45XL’s advanced
waypoint and planning fea-
tures allow you to create
new waypoints and practice
navigation without ever
setting foot outside.
If you create a new way-
point by entering coord i-
nates from a map, you may
want to remark the way-
point’s exact position once
you get there.
To re-define an existing
waypoint’s position coordi-
nates from the waypoint
definition page, simply
highlight the DST field and
p ress ENTER. Use the
LEFT arrow key to set the
distance to 0.00, and press
ENTER to confirm.
The old coordinates will be
replaced by the coordinates
of your present position
(you must have a valid 2D
or 3D position fix).
