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. GETTING STARTED Compass Page 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.
