Go from box to boat to dash with the portable and versatile GPSMAP 478. This combination color chartplotter and land navigator comes preloaded with U.S. marine charts utilizing elements of the latest BlueChart g2 technology, in addition to detailed street-level mapping. Optional weather and sonar capabilities combined with the ability to conveniently add plug-in data cards, let you easily add more maps and features - making this one incredible GPS navigator for land and sea.
Preloaded and Portable
From curbside to dockside, the GPSMAP 478 has you covered - no downloads or computer required. Its built-in marine charts utilize the latest BlueChart g2 technology and feature coverage for all U.S. coastal areas, including Alaska and Hawaii. Our g2 mapping technology offers a smoother, more fluid presentation on your screen.
For road trips, the 478 along with its freshwater counterpart, the GPSMAP 378, 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. 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 478’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.
Sonar Capability
If fishing’s your game, pair the 478 with the GSD 21 remote sounder module to add sonar capability. The GSD 21 is Garmin’s “black box” sounder, which offers 4,000 watts of power peak-to-peak (500 watts RMS) in a dual-frequency transducer (purchased separately).
Plug-and-play Additional Mapping
Optional software available on plug-in Garmin data cards, lets you instantly add new maps to your GPSMAP 478 — without connecting to your computer. Easily customize map data for your adventures on land or sea with our optional MapSource cartography. Plug-in the latest BlueChart g2 data cards to add “real picture” aerial photo reference, detailed coastal roads and points of interest. For inland coverage, try our preprogrammed U.S. Inland Lake data cards. |
