Garmin GPS III Plus - Manual (Page 34)

To view the Highway Page, press PAGE.
The Highway Page provides a graphic highway display that shows your
movement relative to the desired course. The line down the middle of the highway
represents 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 bearing 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 keypad. 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 creating a few more waypoints. Use the Reference section of this manual for
more ideas.
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 desti-
nation, 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.
