Now that we're navigating to an actual destination, let' s move on to the GPS 152 navigation pages
by pressing the PAGE key. The GPS 152 features two different navigation pages: Compass and
Highway. The Compass Page is fi rst. This page provides graphic steering guidance to a destination
waypoint, with an emphasis on the bearing to your destination and current direction of travel, while
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 Compass 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 next waypoint as well as the pointer to the next waypoint are
displayed on the right side of the screen. This page provides better steering guidance than the Highway
Page when travelling at slower speeds and/or when making frequent directional changes. When you
are not navigating to a waypoint, the compass will show your direction of travel as you move but
the arrow will not appear.
Let' s move on to the Highway Page by pressing the PAGE key. The GPS 152' s Highway Page also
provides graphic steering guidance to a destination waypoint. As you head toward your destination,
the middle of the screen provides visual guidance to your waypoint on a moving graphic "highway."
Your present position is at the bottom center of the highway display. The line down the middle of the
highway represents your desired course. As you navigate toward a waypoint, the highway will actually
move, indicating the direction you're off course.
