To view the Highway Page, press PAGE.
The Highway Page provides a graphic highway display that shows your move-
ment relative to the desired course. The line down the middle of the highway repre-
sents your desired course. As you navigate toward your destination, the highway will
actually move, indicating the direction you’re off course. To stay on course, simply
steer toward the center of the highway. As you approach the waypoint, the highway
will end at the final destination. When the waypoint marker is at the bottom center
of the highway display, you’ve arrived at your destination. A track compass also
shows your current track directly above the highway display, making it easy to see at
a glance which way you’re headed.
The pointer arrow at the bottom of the page indicates the direction to the
destination waypoint (bearing) relative to the direction you are moving (track). If the
pointer points straight ahead, you’re heading directly to the waypoint. If not, turn in
the direction of the pointer and the pointer will swing around, pointing straight
ahead as you begin moving toward the destination waypoint. Try moving on course/
off course again using the rocker keypad and watch as the highway display and bear-
ing pointer change.
That’s it! You’ve covered the basics and you’re ready to venture off on your own.
Operating the GPS III is just as simple as you’ve seen here in the Simulator Tour, but
in real applications you won’t need to change speed and track with the rocker key-
pad. That’s all done automatically utilizing information from the GPS satellites as you
move about.
Before ending the tour, try a few experiments of your own, such as going back
to the ‘HOME’ waypoint, retracing your steps utilizing the TracBack feature, or cre-
ating a few more waypoints. Use the Reference section of this manual for more ideas.
To end the Simulator Tour, turn the GPS III off with the red power key.
Use the LEFT/RIGHT keys on
the rocker keypad to move off
course / on course. To return
to your course, steer toward
the highway centerline.
When you reach your destina-
tion, the highway will end at
the waypoint marker. Also
note the ‘distance to next’
waypoint readout. If you pass
the waypoint the pointer will
swing around, pointing down.
