Moving Map Page
The GPS 45XL features a powerful real-time moving
map that can do much more than just plot your course and
route. The map page also provides you with a target cursor
that will let you pan ahead to nearby waypoints, determine
the distance and bearing to any map position, and mark
new waypoints while you navigate.
The map page can be broken down into two sections:
The zoom function and panning control fields are locat-
ed at the top of the screen. There are 12 selectable zoom
ranges from 0.2 to 320 miles or 0.5 to 600 km. These
ranges are measured vertically.
The map portion of the page displays your present
position as a diamond icon, with your track and/or route
displayed as a solid line. Nearby waypoints are represented
as squares, with the waypoint name also listed. You may
select which of these features are shown through the map
setup submenu page (see page 49 for more information).
The four corners of the map page are used to display
various navigation data, including the bearing and distance
to a destination waypoint and your current track and speed
over the ground. The two fields at the top corners of the
map show your bearing and distance to one of three selec-
table destinations: an active destination waypoint; a high-
lighted on-screen waypoint; or the panning target crosshair.
If you are not navigating to a waypoint or using the pan-
ning function, the top data fields will not be displayed.
Your current track and speed are shown at the bottom
corners of the display.

Range Rings
The GPS 45XL has on-
screen range rings to help
you estimate distances rela-
tive to your present position.
The value of each ring is
determined by the current
zoom scale, and is equal to
1/5 of the selected scale.
To turn the range rings dis-
play on or off (the default
setting is off), see the map
setup section instructions on
page 49.
