The GPSMap 76Cx features the powerful SiRF GPS navigation chip for supreme accuracy in all conditions.

You can use the 76Cx's memory card slot with preprogrammed microSD cards from Garmin (sold separately) that provide topographic maps, city streets, and nautical charts. In fact, the unit is compatible with most Garmin MapSource products, including BlueChart, City Navigator, U.S. Topo 24K, and U.S. Topo and Recreational Lakes with Fishing Hot Spots. The unit comes preloaded with an Americas autoroute basemap that provides automatic routing capabilities including highways, exits, and tide data. There's also a preloaded marine point database. You can even get turn-by-turn directions when you're driving, and an integrated trip computer provides odometer, stopped time, moving average, overall average, total time, max speed, and more.

The 76Cx's 2.6-inch, 256-color TFT color display is designed to present mapping and trip information clearly and accurately in any lighting conditions. Plus, the case is lightweight, rugged, and water resistant to IEC 60529 IPX7 standards (can be submerged in one meter of water for 30 minutes). Marine users will also like the fact that the 76Cx floats. When using two AA alkaline batteries, you'll get up to 30 hours of battery life from the unit.

Another key feature of the 76Cx is the 10,000 point automatic track log; 20 saved tracks (500 points each) let you retrace your path in both directions. Meanwhile, there's a large numbers option for easy viewing, as well as a dual-position display mode. The unit also includes built-in celestial tables for best times to fish and hunt, as well as sun and moon calculations. You also get audible alarms for anchor drag, arrival, off-course, proximity waypoint, and clock.

The 76Cx's trip computer provides odometer, stopped time, moving average, overall average, total time, max speed, and more. Meanwhile, a fast processor allows the 60Cx to provide quick auto-routing, turn-by-turn directions, and audio alerts when you use the optional MapSource software, which can be stored on the unit's included 128 MB microSD card. Downloading information is quick with the USB or serial port interfaces. Using the dedicated serial port, the 76Cx can share navigation instructions with repeaters, plotters, and autopilots.

If you like the features of the 76Cx but require an electronic compass and a barometric altimeter, check out the Garmin GPSMap 76CSx.
