Product Overview.
Garmin GPSMAP 478 has a same physical dimension with GPSMAP 276. The technical ability is almost similar, the features that make the different are: GPSMAP 478 equipped with XM WX weather & Radio (for US area), pre installed marine charts (covering US coastal area) and voice prompts capability. So, we can use the full function of this GPS if we are living in the USA and also have a boat to traveling with. If you only use the GPS mainly in the road and sometimes go to the water, GPSMAP 276C is a better choice and much cheaper (almost US$ 400 cheaper than GPSMAP 478).
Product Description
Go from box to boat to dash with the portable and versatile WAAS enabled, 12 parallel channel Garmin GPSMAP 478 GPS receiver. This combination color chartplotter and land navigator comes preloaded with United States marine charts utilizing elements of the latest BlueChart g2 technology, in addition to detailed street level mapping. With a 3.8-inch diagonal, 480 x 320, 256-color TFT screen with adjustable LED backlight, this navigation system supplies easy to read information to help chart your boating and driving trips. It also offers optional weather and sonar capabilities and gives you the ability to use plug in data cards, so you can instantly add new maps to your GPSMAP 478 without connecting to your computer. Designed for use both on land and in seawater, the GPSMAP 478 is ready to go, right out of the box--no downloads or computer required.
The GPSMAP 478's built in marine charts use the latest BlueChart g2 technology for a smoother, more fluid presentation on your screen, and feature coverage for all U.S. coastal areas, including Alaska and Hawaii. For road trips, this system comes preloaded with City Navigator NT detailed street maps for North America and offers automatic routing with voice guidance to help get you where you're going quickly and easily. The GPSMAP 478 also includes an industry leading database with more than six million points of interest including hotels, restaurants, gas stations, marinas, attractions and more. This system also tracks 10,000 points and the automatic track log saves up to 15 points. For additional flexibility, an included marine mount and automotive kit make it a snap to transfer the unit from boat to car.
With the GPSMAP 478, weather and audio options travel with your plotter, whether you're navigating on land or sea. In fact, this system can display real-time weather information on the high-resolution 256-color sunlight-readable TFT display. To help make sure you're prepared for whatever comes your way, view NEXRAD radar, storm cells, wind speeds, surface temperatures, forecasts and more than a dozen other weather attributes, so you can spend more time enjoying the water and less time worrying about the weather. And 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.
