This unit has an auto zoom feature that eliminates much of the button 

pushing common with other brands of GPS receivers. It works in con-

junction with the navigation features.  
First, start navigation to a waypoint. (See the waypoint section for 

more information on navigating to a waypoint.) Then, with the auto 

zoom mode on, the unit zooms out until the entire course shows, from 

the present position to the destination waypoint. As you travel toward 

the destination, the unit automatically begins zooming in — one zoom 

range at a time — always keeping the destination on the screen.

screen into a GPS plotter); turn off or on the pop-up map info boxes; 

draw the map boundaries or boxes around the areas of high detail; or 

fill land areas with gray. You can also turn on or off Map Overlays, 

which display latitude and longitude grid lines or range rings on the 

map. This menu also lets you select Navionics Maps.
