Garmin GPSMAP 640

Navigate by land and by sea with the Garmin GPSMAP 640. This full-featured marine chartplotter pulls double duty with an automotive mode that’s ready to go as soon as you reach the shore when loaded with optional City Navigator NT road maps for North America. And to make sure you always know the way, the GPSMAP 640 comes standard with a high-sensitivity GPS receiver and brilliant, high-resolution touchscreen display.

Powerful and Portable

Featuring a marine and an automotive mode, a high-sensitivity GPS receiver, and a rugged case with waterproof (IPX7) design, the GPSMAP 640 is ready for your next outing. The GPSMAP 640 effortlessly shifts gears between marine and automotive modes. When supported by the marine mount, you’ll have at-a-glance access to your marine data. And when used with the optional automotive mount and City Navigator NT for North America map data, the automotive mode is automatically activated and the GPSMAP 640 becomes a robust on-the-road navigator.

Designed to Shine

With a brilliant 5.2-inch WVGA touchscreen display, and an intuitive interface, you’ll have everything you need to navigate with confidence. The GPSMAP 640 comes preloaded with coastal bluecharts and a worldwide satellite basemap for ‘view-from-space’ imagery of shorelines and other surface features in the area.

By Sea

Preloaded with g2 coastal bluecharts
In marine mode, the GPSMAP 640 provides 3D ‘mariner’s eye view’ above the waterline, ‘fish eye view’ below the waterline, and Auto Guidance technology that searches chart data to suggest the best passage with optional BlueChart® g2 Vision data. And you’ll always get the big picture with a worldwide basemap that comes standard on the GPSMAP 640. The GPSMAP 640 is also NMEA 0183 compliant, so it can be easily added to an existing marine network. And with access to fishing charts, tide and current data, marine services, coastal roads and more via optional BlueChart g2 Vision data, you’ll always be in the know while you’re on the water.

By Land

In automotive mode, the GPSMAP 640 provides turn-by-turn directions that speak street names (with required City Navigator NT for North America data). And route planning has never been easier. Whether you’re searching for boat shops or bait shops, you’ll be able to plan the quickest and most efficient route. You can also create custom points of interests (POIs) and set up proximity alerts to let you know what’s in your path as you travel down the road.
