Using the Highway Page
The GPS 126/128’s Highway Page provides graphic
steering guidance to a destination waypoint, with a
greater emphasis on the straight-line desired course and
the distance and direction you are off course. The bear-
ing and distance to a waypoint–along with your current
track and speed–are displayed at the top of the screen.
The middle of the screen provides visual guidance
to your waypoint on a moving graphic “highway.” Your
present position is represented by the diamond in the
center of the CDI scale. The line down the middle of
the highway represents your desired track. As you navi-
gate toward a waypoint, the highway will actually
move—indicating the direction you’re off course—rela-
tive to the position diamond on the CDI scale. When
the highway is pointing straight up the screen, the way-
point is directly ahead. If the destination waypoint is to
the left, the top of the highway will lead to the left, and
vice versa. To stay on course, simply steer in the direc-
tion the highway leads (left or right) until the highway
leads straight up the page.
Below the graphic highway is the “pointer.” The
pointer shows the direction of the waypoint relative to
the direction you are moving.
Below the pointer are two user-selectable fields.
If you do get off the desired course by more than
1/5th of the selected CDI range, the exact distance you
are off course will be displayed where the CDI scale set-
ting normally appears. If you get too far off course (the
highway has disappeared), a message box will appear to
indicate what course to steer to get back on course. (For
information on setting this scale, see pg. 48.) When the
distance reading reaches 0, you’ve reached your destina-
tion.

In this example, the
Highway Page indicates
that you are off course to
the left. Steer right to get
back on course. Notice the
highway always shows the
direction to turn. If the
highway leads straight up
the page, you should con-
tinue in your current
direction.
If you get too far off
course, a message box will
appear to indicate what
course to steer to get back
on course most efficiently.
