If anarea has an unknown water depth or an unknown obstacleheight, the Auto Guidance path is not calculated in that area. Ifan area at the beginning or the end of an Auto Guidance path isshallower than the Preferred Depth or lower than the VerticalClearance settings, the Auto Guidance path may not becalculated in that area, depending on the map data. On thechart, the course through those areas appears as a gray line ora magenta and gray striped line. When your boat enters one ofthose areas, a warning 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.Preferred Depth: Sets the minimum water depth, based onchart depth 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 destinations18 Navigation with a Chartplotter
