Garmin GPS 125 Sounder - Manual (Page 17)

Using the Highway Page
The GPS 125 Sounder’s Highway Page provides
graphic steering guidance to a destination, with an
emphasis on a straight-line course to the desired way-
point and the distance and direction you are off course.
The bearing and distance to a waypoint, along with
your current track and speed are displayed at the top of
the screen, with your estimated time enroute (ETE) and
velocity made good (VMG), or the speed you are
approaching your destination, shown at the bottom.
As you head toward your destination, the middle
section of the screen provides visual guidance to your
waypoint on a moving graphic “highway”.
Your present position is represented by the dia-
mond in the center of the course deviation scale. The
line down the middle of the highway represents your
desired track.
As you navigate toward a waypoint, the highway
will actually move, indicating the direction you’re off
course, relative to the position diamond on the CDI
scale. When the highway is pointing straight up the
screen, the waypoint is directly ahead. If the destina-
tion waypoint is to the left, the top of the highway will
lead toward the left, and vice versa. To stay on course
simply steer in the direction the highway leads (left or
right) until the highway leads straight up the page.

A waypoint is directly
ahead when the highway is
pointing straight up. In the
above example, the way-
point is to the right (111º) of
our present course (100º).
Turn right until the highway
points straight up the
screen.
