Garmin GPS III Plus - Manual (Page 21)

The GPS III+ features two different navigation pages: Compass and Highway. The
Compass Page is first. This page provides graphic steering guidance to a destination
waypoint, with an emphasis on the bearing to your destination and current direction
of travel. (The Highway Page places greater emphasis on the straight-line desired
course and the distance and direction you are off course.) 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 compass ring and pointer arrow
work independently to show—at a glance—the direction of your movement and the
direction to your destination. For instance, 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 current speed and distance to the destination waypoint are displayed at
the top of the screen. The bottom of the page displays the time to the destination
waypoint and the current time. This page provides better steering guidance than
the Highway Page when travelling at slower speeds and/or when making frequent
directional changes.
If the bearing pointer points
up, your are going directly
to your destination. If not,
turn toward the arrow until
it points up, then continue in
that direction.
The ‘Big Numbers’ option
(available from the Compass
Page Options) shows a much
smaller compass display and
larger data field characters.
