screen into a GPS plotter — turn on or off pop-up map info boxes, draw
map boundaries or boxes around areas of detail and fill land areas with
gray. You can also turn on or off Map Overlays, which display range
rings and latitude and longitude grid lines on the map. Navionics maps
also may be accessed on the Map Data menu. For detailed instructions,
see the Navionics Charts entry in this section.
