The Auto Guidance feature is based on electronic chart 

information. That data does not ensure obstacle and bottom 

clearance. Carefully compare the course to all visual sightings, 

and avoid any land, shallow water, or other obstacles that may 

be in your path.
NOTE: Auto Guidance is available with premium charts, in some 

areas.
