[. . . ] Delete allows you to delete a route from a list of previously-saved routes. Travel allows you to select a previously-saved route to use as the current route; this menu setting also begins navigation on this route. Info displays information about the route, including the distance and bearing from each waypoint to the next. 58 Chart Orientation Chart Orientation allows you to select whether the Chart and Combo Views should be drawn North-Up or Course-Up. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Chart Orientation setting. (North-Up, Course-Up, Default = North-Up) NOTE: The Chart Orientation setting does not apply to the Bird's Eye View. North Reference North Reference allows you to have bearings displayed with one of two orientations: True North or Magnetic North.

(0° to 89°, Default = 0°) 59 Trackpoint Interval Trackpoint Interval allows you to select the time period between trackpoints. The current track can only contain up to 20, 000 trackpoints, so longer time periods cause the track to extend back further in time, but will be less detailed. NOTE: Trackpoint Interval works in conjunction with Track Min Distance. Both conditions must be met before a trackpoint is added to the current track. To change the Trackpoint Interval setting: 1. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Trackpoint Interval setting. (1 second, 5 seconds, 10 seconds, 15 seconds, 30 seconds or 60 seconds, Default = 15 seconds) NOTE: During slow travel or drift, setting both Trackpoint Interval and Track Min Distance to small values will allow you to increase the track resolution. Track Min Distance (Advanced) Track Min Distance allows you to set a minimum distance of travel before a trackpoint is added to the track. The Track Min Distance menu choice is only available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). NOTE: Track Min Distance works in conjunction with Trackpoint Interval. Both conditions must be met before a trackpoint is added to the current track. To change the Track Minimum Distance setting: 1. Make sure you are in Advanced User Mode, then highlight Track Min Distance on the Navigation main menu. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Track Min Distance setting. (1 to 300 feet or 1 to 100 meters [International Units only], Default = 16 ft, 5 m) NOTE: During slow travel or drift, setting both Trackpoint Interval and Track Min Distance to small values will allow you to increase the track resolution. 60 Map Datum (Advanced) Map Datum allows you to change the map coordinate system used by the 100 SeriesTM Fishing System to match those of a paper map. The Map Datum menu choice is only available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). Make sure you are in Advanced User Mode, then highlight Map Datum on the Navigation main menu. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Map Datum setting. (Default = WGS 84) Course Projection Line Course Projection Line allows you to display or hide an arrow extending from the bow of the boat that projects your current course, and shows where the boat will go if you continue on your present course. [. . . ] Generally, all GPS units have a limited number of Track Points that can be saved before the unit runs out of memory and begins erasing the first track points saved. Because of this, the user can adjust the Track Point Interval menu to increase the amount of time between when points are saved, and thus extend the distance covered by a track. Tracks can also be permanently saved to memory, and re-displayed at the user's option. Track Line (TRK): The Track Line is the desired line of travel between two waypoints, and represents the most efficient path between the two points because it is a straight line. [. . . ]
