Notice the information on the map display is slowly moving? That’s how it would
look in actual use as well. The background map information and nearby waypoints
will move across the screen, while your current position remains fixed in the center.
The other primary navigation screens are the Compass and Highway pages, with
the Compass Page appearing first in the sequence of main pages.
To view the Compass Page, press PAGE.
The GPS III’s Compass Page provides graphic steering guidance to a destination
waypoint. The middle of the page features a rotating ‘compass ring’ that shows your
course over ground (track) while you’re moving, and a bearing pointer that indicates
the direction of the destination (bearing) relative to the course over ground. The com-
pass ring and pointer arrow work independently to show—at a glance—the direction
of your movement and the direction to your destination. If the arrow points up, you
are going directly to the waypoint. If the arrow points any direction other than up, turn
toward the arrow until it points up—then continue in that direction. The distance to
the next waypoint, time to the next waypoint and current speed are displayed to the
right of the graphic compass display. To see how all this works on our simulated trip,
let’s head off course and watch the displays change.
To move off course / on course in simulator mode, use the LEFT/RIGHT
keys on the rocker keypad.
The background map moves
while keeping your current
position at the center of the
map display.
The Compass Page will also
guide you to your destination.
The rotating ‘compass ring’
shows the direction of travel
(track) and the arrow points
to your destination (bearing).
