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 > Navigation > Auto Guidance > ShorelineDistance > Normal.3 Select a destination that you have navigated to previously.4 Select Navigate To > Auto Guidance.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 > 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 > Far.• If the turns in the Auto Guidance line are too wide, selectSettings > Navigation > Auto Guidance > ShorelineDistance > Near.7 If you selected Near or Far in step 6, review the placement ofthe 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 determinewhether the line safely avoids known obstacles and the turnsenable efficient 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.Auto Guidance Path ConfigurationsCAUTIONThe Safe Depth and Vertical Clearance settings influence howthe chartplotter calculates an Auto Guidance path. If an area hasan unknown water depth or an unknown obstacle height, theAuto Guidance path is not calculated in that area. If an area atthe beginning or the end of an Auto Guidance path is shallowerthan the Safe Depth or lower than the Vertical Clearancesettings, the Auto Guidance path may not be calculated in thatarea, depending on the map data. On the chart, the coursethrough those areas appears as a gray line or a magenta andgray striped line. When your boat enters one of those areas, awarning message appears.NOTE: Auto Guidance is available with premium charts, in someareas.NOTE: Not all settings apply to all maps.You can set the parameters the chartplotter uses whencalculating an Auto Guidance path.Safe Depth: Sets the minimum water depth, based on chartdepth data, that your boat can safely travel over.NOTE: The minimum water depth for the premium charts(made before 2016) is 3 feet. If you enter a value of less than3 feet, the charts only use depths of 3 feet for Auto Guidancepath calculations.Vertical Clearance: Sets the minimum height of a bridge orobstacle, based on chart data, that your boat can safelytravel under.Shoreline Distance: Sets how close to the shore you want theAuto Guidance path to be placed. The Auto Guidance pathmay 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 path using one or more familiar destinationsthat require navigation through a narrow waterway (Adjustingthe Distance from Shore, page 14).BoundariesBoundaries allow you to avoid or remain in designated areas ina body of water. You can set an alarm to alert you when youenter or exit a boundary.14 Navigation with a Chartplotter
