Map Page
The
Map Page
acts as a window. It allows you to
view your position, the “path” you have traveled over,
and nearby navaids, cities and waypoints.
A diamond icon in the center of the screen repre-
sents your current position. As you move, you will see
a thin line - called a
track log
- appear along the path
you have just covered.
The GPS 48 contains a built–in marine database
that displays city locations and nautical navaids on the
moving map. The database is covered on pages 21-22.
The bottom corners of the map will always display
your current track and speed. When going to a way-
point, highlighting an on-screen waypoint, or using the
panning target crosshair, the corresponding distance
and bearing are shown at the top corners of the map.
The top of the screen contains the zoom, pan, and con-
figuration fields.
Navigation Page
A navigation page gives you steering guidance
when going to a waypoint. The GPS 48 has two navi-
gation page choices: the Compass Page and the
Highway Page. The Compass Page is the default and
briefly explained here. The Highway Page is covered on
pages 28 and 31.
The
Compass Page
shows the destination way-
point at the top of the page with the bearing (BRG) and
distance (DST) to the waypoint shown below. The cen-
ter of the page contains a compass ring and arrow to
show you the direction of the waypoint from the direc-
tion you are moving. The bottom of the page gives
your track (TRK), speed (SPD), and a selectable field
for estimated time to arrival (ETA), estimated time
enroute (ETE), course to steer (CTS), crosstrack error,
(XTK), velocity made good (VMG), or turn bearing
(TRN).
Menu Page
The last primary page is the
Menu Page.
The
Menu Page gives you access to the GPS 48’s waypoint
management, route, track log, and setup features
through a list of submenus.

The Map Page shows your
progress on a moving map
plotter and gives a
bird’s–eye–view of sur-
rounding naviads, cities
and waypoints.
