GPSMAP 820

The 8” colour GPSMAP 820 keyed chartplotter has a preloaded worldwide basemap. The built-in 10 Hz GPS/GLONASS receiver updates your position and heading 10 times per second.
With NMEA 2000® support for autopilot capability, engine data, SiriusXM® Weather and more, the GPSMAP 820 is compatible with LakeVü HD Ultra, BlueChart g2 and BlueChart g2 Vision. It also supports all Garmin marine radar.
For even more functionality, wirelessly connect to Apple® (mobile digital device) for BlueChart® Mobile. The chartplotter includes 2 SD™ data card slots, allowing for gigabytes of storage. It can be flat, flush or bail mounted.



Networking
The GPSMAP 820 offers select networking capabilities that allow you to share features with other compatible GPSMAP units, such as radar, GCV 10 DownVü and SideVü scanning sonar, supplemental maps, and user data, such as waypoints, routes and tracks.

Special Sailing Features
Supported sailing features include laylines, enhanced wind rose, heading and course-over-ground lines, and true wind data fields.

Enhanced Auto Guidance
Just enter the location where you want to go and patented Garmin Auto Guidance technology instantly searches through relevant charts to create a safe virtual pathway on the display that helps you avoid low bridges, shallow water and other charted obstructions en route. Better still, with enhanced Version 2.0, you now have access to even more features and capabilities. You’re able to adjust the calculated Auto Guidance pathway by inserting “via” points at interim stops or landmarks along your desired route. You can easily review hazard points along your calculated path. And you can even engage your compatible Garmin autopilot to follow the Auto Guidance route, automatically. Other 2.0 enhancements give you the ability to calculate arrival times at any point on your route (great for timing arrivals to correspond with bridge openings and other time-critical events). Better still, you can now save your plotted Auto Guidance paths for future navigation by backing them up on an SD™ card with your BlueChart® g2 Vision® or Lake Vü™ HD Ultra cartography¹.



GPX Waypoints Transfer
If you have waypoints, tracks or frequently used routes stored on another manufacturer’s GPS product – or on a Garmin handheld device – now it’s easier than ever to transfer those items to your new Garmin chartplotter, via industry-standard GPX software formatting. GPX is an open standard format for GPS data exchange across platforms and applications. With this easy-to-use interface technology, Garmin has taken “no waypoint left behind” to a whole new level of trade-up convenience.

Panoptix™ Down Transducer
With 1 Panoptix Down transducer, you get 3 remarkable views, allowing you to actually see fish and bait swimming around under your boat – in real time. You can even see fish in the water column in 3-D, from the bottom to the surface. You can be stationary yet still see things in 3-D below your boat.
