Your unit has a worldwide imagery map, a built-in detailed map 

of US inland lakes, or BlueChart g2 cartography for either the US 

shoreline or a specific country.

• 

Navigation Chart—displays all relevant navigation data 

available on your preloaded maps, including buoys, lights, cables, 

depth soundings, marinas, and tide stations in an overhead view.

•  Mariner’s Eye—a bird’s eye view from above and behind 

your boat, for a visual navigation aid.

  NOTE: If you are using a GPSMAP 520/520s or 525/525s, you 

must insert an optional BlueChart g2 Vision preprogrammed SD 

card to view detailed Navigation and Mariner’s Eye charts.

 preprogrammed SD cards.

•  Fishing Chart—removes navigational data from the preloaded 

map, while leaving the bottom contours and depth soundings. 

(This is not available on the 530/530s and 535/535s - all contour 

lines and depth soundings appear on the Navigation chart.)

•  Fish Eye 3D—an underwater view that visually represents the 

sea floor or lake bottom according to the chart’s information.

(This is available for select lakes on 530/530s and 535/535s 

units without an additional card).

Use the navigation chart to plan your course, view map information, 

and as a navigational aid.

  NOTE: For GPSMAP 520/525 units, you must insert an optional 

BlueChart g2 Vision preprogrammed SD card for your region to 

view detailed navigation charts.
