42 GPSMAP® 585 Plusduring navigation.Auto Guidance Path ConfigurationsCAUTIONThe Preferred Depth and Safe Height settings influence how the chartplottercalculates an Auto Guidance path. If an area has an unknown water depthor an unknown obstacle height, the Auto Guidance path is not calculated inthat area. If an area at the beginning or the end of an Auto Guidance path isshallower than the Preferred Depth or lower than the Safe Height settings,the Auto Guidance path may not be calculated in that area, depending on themap data. On the chart, the course through those areas appears as a grayline or a magenta and gray striped line. When your boat enters one of thoseareas, a warning message appears.NOTE: Auto Guidance is available with premium charts, in some areas.NOTE: Not all settings apply to all maps.You can set the parameters the chartplotter uses when calculating an AutoGuidance path.Preferred Depth: Sets the minimum water depth, based on chart depth data,that your boat can safely travel over.NOTE: The minimum water depth for the premium charts (made before2016) is 3 feet. If you enter a value of less than 3 feet, the charts only usedepths of 3 feet for Auto Guidance path calculations.Safe Height: Sets the minimum height of a bridge or obstacle, based on chartdata, that your boat can safely travel under.Shoreline Distance: Sets how close to the shore you want the AutoGuidance path to be placed.
