The GPSMAP 276C is an all-in-one, versatile, color chartplotter and automobile navigator - perfect for land or water. This portable GPS navigator features a 256-color TFT display that's easy to read in bright sun along with a built-in basemap and auto routing to provide you with turn-by-turn directions to the marina for a day of boating.

On water, the GPSMAP 276C is a dependable, color chartplotter with a built-in Autoroute basemap enhanced by Garmin's marine cartography. It accepts pre-programmed or user programmed data cards with MapSource® BlueChart® for offshore detail or Recreational Lakes with Fishing Hot Spots® for detail of inland lakes.

In addition, the GPSMAP 276C supports external NMEA sources for water depth, water temperature, and water speed through two serial interfaces. The unit also features a new Course Deviation Indicator (CDI) - an advanced navigation tool commonly found on aircraft, but equally practical in the marine environment. The CDI quickly indicates if a boat has veered off course.

On land, the GPSMAP 276C’s Americas Autoroute basemap features interstates and major highways. With an optional automotive kit that includes MapSource City Select® software, data card, friction mount, and 12-volt power adapter with speaker, drivers can receive voice-prompted turn-by-turn directions to addresses and points of interest throughout the United States and Canada.

For map transfer or software updates, the GPSMAP 276C features a fast USB-PC interface. The unit is also powered by a rechargeable lithium-ion battery pack, or a standard 110-volt AC plug.
