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 compass 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 indicated 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 userselectable 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. REFERENCE Compass Page 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. Pointer (Bearing to Destination) Compass Ring Current Speed and Distance to Waypoint Time to Waypoint and Current Time If you pass your destination waypoint, the bearing pointer will swing around 180º and the 'Dist to Next' waypoint will increase. 43
