Garmin GPSMap 276C

Discontinued. Find more Marine GPS units here>

The GPSMAP 276C is a 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 land, the GPSMAP 276C's Americas Autoroute basemap features interstates and major highways. With an optional automotive kit that includes either MapSource City Select or MetroGuide Canada 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 or Europe. RAM mounts and a bare-wire power/audio cable are available for motorcycle use, and the area calculation feature further adds to the versatility of the GPSMAP 276C.

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 Spotsfor 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.

ADD A DEPTH SOUNDER! The GPSMAP 276C with v3.00 and later software will now support the GSD 20 remote sounder module. Visit for the latest in operating software updates.

For map transfer or software updates, the GPSMAP 276C features a fast USB-PC interface. A Garmin data card is required for download of MapSource map data, or the unit can be used with preprogrammed BlueChart data cards. The 276C is powered by a rechargeable lithium-ion battery pack, a 12-volt power adapter, or a standard 110-volt AC plug."
