When set to Auto, the overlay numbers appear only when that category is active. • Cruising: GPS speed and GPS heading. ◦ Data Bar Setup-specify the position of the data bar on the Navigation chart, and specify the contents of the fields. • Navigation: GPS speed, distance to destination, arrival (time), off course, bearing (to destination), and GPS heading. When set to Auto, these numbers appear only when navigating to a destination. ◦ Data Bar Setup-toggle the Route Leg data field (shows additional route information) and specify how each data field provides navigation information (by time or by distance). • Fishing: Depth, water temperature, and water speed.
