Map Datum: Sets the coordinate system on which the map isstructured. Do not change this setting unless you are using amap or chart that specifies a different map datum.Time: Sets the time format, time zone, and daylight saving time.Navigation SettingsNOTE: Some settings and options require additional charts orhardware.Select Settings > Preferences > Navigation.Route Labels: Sets the type of labels shown with route turns onthe map.Turn Transition: Adjusts how the chartplotter transitions to thenext turn or leg or the route. You can set the transition to bebased on time or distance before the turn. You can increasethe time or distance value to help improve the accuracy ofthe autopilot when navigating a route or an Auto Guidanceline with many frequent turns or at higher speeds. Forstraighter routes or slower speeds, lowering this value canimprove autopilot accuracy.Auto Guidance: Sets the measurements for the Safe Depth,Safe Height, and Shoreline Distance, when you are usingsome premium maps.Route Start: Selects a starting point for route navigation.Auto Guidance Line ConfigurationsCAUTIONThe Safe Depth and Safe Height settings influence how thechartplotter calculates an Auto Guidance line. If an area has anunknown water depth or an unknown obstacle height, the AutoGuidance line is not calculated in that area. If an area at thebeginning or the end of an Auto Guidance line is shallower thanthe safe water depth or lower than the safe obstacle height, theAuto Guidance line is not calculated in that area. On the chart,the course through those areas appears as a gray line. Whenyour boat enters one of those areas, a warning messageappears.NOTE: Auto Guidance is available with premium charts, insome areas.You can set the parameters the chartplotter uses whencalculating an Auto Guidance line.Safe Depth: Sets the minimum depth (chart depth datum) thechartplotter uses when calculating an Auto Guidance line.Safe Height: Sets the minimum height (chart height datum) of abridge that your boat can safely travel under.Shoreline Distance: Sets how close to the shore you want theAuto Guidance line to be placed. The Auto Guidance linemay move if you change this setting while navigating. Theavailable values for this setting are relative, not absolute. Toensure that the Auto Guidance line is placed the appropriatedistance from shore, you can assess the placement of theAuto Guidance line using one or more familiar destinationsthat require navigation through a narrow waterway(page 23).Adjusting the Distance from ShoreCAUTIONThe Auto Guidance feature is based on electronic chartinformation. That data does not ensure obstacle and bottomclearance. Carefully compare the course to all visual sightings,and avoid any land, shallow water, or other obstacles that maybe in your path.NOTE: Auto Guidance is available with premium charts, insome areas.The Shoreline Distance setting indicates how close to the shoreyou want the Auto Guidance line to be placed. The AutoGuidance line may move if you change this setting whilenavigating. The available values for the Shoreline Distancesetting are relative, not absolute. To ensure the Auto Guidanceline is placed the appropriate distance from shore, you canassess the placement of the Auto Guidance line using one ormore familiar destinations that require navigation through anarrow waterway.1 Dock your vessel or drop the anchor.2 Select Settings > Preferences > Navigation > AutoGuidance > Shoreline Distance > Normal.3 Select a destination that you have navigated to previously.4 Select Navigate To > Guide To.5 Review the placement of the Auto Guidance line, anddetermine whether the line safely avoids known obstaclesand the turns enable efficient travel.6 Select an option:• If the placement of the Auto Guidance line is satisfactory,select Menu > Navigation Options > Stop Navigation,and proceed to step 10.• If the Auto Guidance line is too close to known obstacles,select Settings > Preferences > Navigation > AutoGuidance > Shoreline Distance > Far.• If the turns in the Auto Guidance line are too wide, selectSettings > Preferences > Navigation > Auto Guidance> Shoreline Distance > Near.7 If you selected Near or Far in step 6, review the placementof the Auto Guidance line, and determine whether the linesafely avoids known obstacles and the turns enable efficienttravel.Auto Guidance maintains a wide clearance from obstacles inopen water, even if you set the Shoreline Distance setting toNear or Nearest. As a result, the chartplotter may notreposition the Auto Guidance line, unless the destinationselected requires navigation through a narrow waterway.8 Select an option:• If the placement of the Auto Guidance line is satisfactory,select Menu > Stop Navigation, and proceed to step 10.• If the Auto Guidance line is too close to known obstacles,select Settings > Navigation > Auto Guidance >Shoreline Distance > Farthest.• If the turns in the Auto Guidance line are too wide, selectSettings > Navigation > Auto Guidance > ShorelineDistance > Nearest.9 If you selected Nearest or Farthest in step 8, review theplacement of the Auto Guidance line, and determine whetherthe line safely avoids known obstacles and the turns enableefficient travel.Auto Guidance maintains a wide clearance from obstacles inopen water, even if you set the Shoreline Distance setting toNear or Nearest. As a result, the chartplotter may notreposition the Auto Guidance line, unless the destinationselected requires navigation through a narrow waterway.10Repeat steps 3 through 9 at least once more, using adifferent destination each time, until you are familiar with thefunctionality of the Shoreline Distance setting.Communications SettingsNMEA 0183 SettingsSelect Settings > Communications > NMEA 0183 Setup.Port Type: See page 24.Output Sentences: See page 24.Posn Precision: Adjusts the number of digits to the right of thedecimal point for transmission of NMEA output.XTE Precision: Adjusts the number of digits to the right of thedecimal point for NMEA crosstalk error output.Device Configuration 23
