Whenever a destination waypoint(s) has been selected, the GPS III’s Compass
Page will guide you to your destination with digital readouts and a graphic com-
pass display, which includes a bearing pointer. Use this page (instead of the
Highway Page) when travelling at slower speeds, when making frequent directional
changes, or where straight line navigation is not possible due to obstructions or
terrain.
The middle of the page features a rotating ‘compass ring’ that shows your course
over ground (track) while you’re moving. (Your present course over ground is indicat-
ed at the top of the compass ring.) A bearing pointer, in the middle of the compass
ring, 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.
Along the right side of the page (top, when display is vertical) are four user-
selectable data fields that display current speed, distance and time to next waypoint,
and current time (defaults). Each data field may be configured to display any one of
twenty-five data options.
The bearing pointer indicates
the direction (bearing) to your
destination. If the arrow points
any direction other than up,
turn toward the arrow until it
points up.
If you pass your destination
waypoint, the bearing pointer
will swing around 180º and
the ‘Dist to Next’ waypoint
will increase.
