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 a bearing pointer (defaults). The bearingpointer always points to the destination waypoint (or the next waypoint when usinga route) relative to the direction you are moving (track). If the bearing pointer pointsstraight ahead, you are heading directly to your destination. If the bearing pointerpoints any direction other than up, turn toward the arrow until it points up—thencontinue in that direction. Each data field may be configured to display any one oftwenty-three data options.The graphic heading compass at the top of the page indicates the direction youare moving (track).
