Both the GPSMAP 520 and GPSMAP 520s feature crisp, sunlight readable VGA displays driven by high-speed processors. They offer exceptional detail, fast redraw rates, and the most realistic photo-enhanced cartography ever seen in their class of fixed-mount electronics. Options such as true 3D-view mapping, both above and below the waterline, plus available auto guidance safe-passage routings help simplify navigation. And an optional SD card slot makes it easy to plug in extra chart regions and features, as well as panoramic aerial photo reference.

BlueChart g2 Vision cards provide:
- High-resolution satellite imagery when overlaid on the chart, will provide the mariner with unparalleled situational awareness
- Aerial reference photography provides "real world" photos of ports, harbors, marinas, waterways, navigation landmarks and other points of interest, offering the mariner another powerful tool for navigating unfamiliar waters
- Mariner's Eye view - Provides the mariner with a 3-D perspective of chart information for a quick, reliable and easy position fix.
- Fish Eye view - 3D perspective below the water line for displaying bottom contours based on bathymetric charting data
- Auto guidance technology will search the attributes of all relevant charts to suggest the best course for navigation
- Fishing charts, tides, currents, marine services, coastal roads and points of interest detail
