• With the Garmin GPSMAP 640, you'll get a full-featured marine chartplotter and an on-the-road navigator that comes ready to go with preloaded BlueChart® g2 Vision data and City Navigator NT road maps for North America. The GPSMAP 640 comes standard with a high-sensitivity GPS receiver and brilliant, high-resolution touchscreen display so you'll always know the way whether you're on land or at sea.
• In marine mode, the GPSMAP 640 brings you tides and currents, depth contours, navaids, port plans, marine services and points of interest (POIs) via preloaded BlueChart g2 marine data. And with optional BlueChart g2 Vision cards, you'll get 3D "mariner's eye view" above the waterline and "fish eye view" below the waterline. You'll also benefit from Auto Guidance technology that searches chart data to suggest the best passage. The GPSMAP 640 is also NMEA 0183 compliant, so it can be easily added to an existing marine network.
