Preloaded and Portable
From curbside to dockside, the GPSMAP 378 has you covered - no downloads or computer required. Its preloaded inland lake maps boast 10-meter resolution for more than 3200 lakes - many with depth contours. In addition, these built-in freshwater maps provide shoreline detail, river and creek channels, islands, boat ramps, campgrounds and more for tens of thousands of lakes across the continental U.S. - giving you the freedom to boat and fish anywhere in the states. These maps also show streams and rivers, tide stations and predictions, a wrecks and obstructions database, and U.S. Coast Guard aids to navigation. For road trips, the 378 along with its saltwater counterpart, the GPSMAP 478, come preloaded with City Navigator NT detailed street maps for North America and include automatic routing with voice guidance along with an industry-leading database with more than six million points of interest - including hotels, restaurants, gas stations, marinas, attractions and more. These street maps are seamlessly integrated with the 378's lake maps. An included marine mount and automotive kit make it a snap to transfer the unit from boat to car.

Up-to-date Weather
See real-time weather displayed on the 378's high-resolution 256-color sunlight-readable TFT display with the purchase of the GXM 30 antenna (sold separately) and subscription to XM WX Satellite Weather. View vital weather data, such as NEXRAD radar, storm cells, wind speeds, surface temperatures, forecasts and more than a dozen other weather attributes directly on the unit's display - so you can spend more time enjoying the water and less time worrying about the weather.

With the GXM 30 antenna, you also have the option of receiving XM Satellite Radio's 150 plus channels of commercial-free music, sports, news, talk and entertainment programming. Weather and audio options travel with your plotter, whether you're navigating on land or sea.
