Marking and Saving Waypoints
Knowing your present position is only part of any navi-
gation equation. You also need to keep track of where
you’ve been and where you are going. Waypoints serve as
electronic markers that let you keep track of starting points,
destinations, navaids and any other important position.
The GPS 45XL allows you to mark, store and use up to
250 waypoints. A waypoint position can be entered by tak-
ing an instant electronic fix or by manually entering a coor-
dinate or range and bearing in reference to an existing way-
point. If you try to mark a waypoint without having a posi-
tion fix, you’ll be notified with a ‘No GPS Position’ message.
To mark your present position:
1. Press the
M
key to capture your position.
The mark position page will appear, showing the cap-
tured position and a default 3-digit waypoint name.
To change the default position name :
1. Press the
U
key twice to move the field highlight from
the ‘save’ field to the name field.
2. Press
E
to begin entry of the name. Pressing the
L
key will clear any existing data.
3. Use the
U
and
D
keys to enter a value in the appro-
priate character field, and use the
L
and
R
keys to move
to each character position.
4. Press
E
to confirm the waypoint name. The field high-
light will move to the ‘route’ field.
If you’d like to add this waypoint to a route:
1. Press the
E
key.
2. Use the
U
or
D
keys to enter a route number.
3. Press the
E
key to confirm the route number.
4. Press the
E
key again to save the waypoint.
If you do not want to add this waypoint to a route:
1. Highlight the ‘save’ field and press the
E
key.
