Product Details

Garmin GPSMAP 478 Portable GPS Navigation Unit - 0100054300

Go straight from the box to your boat to your vehicle with the portable GPSMAP 478. Along with its counterpart, the GPSMAP 378, this combination color chartplotter and street navigator comes preloaded with detailed marine maps and detailed street maps, so you can find your way anywhere.

Head Straight for the Water
Ready for action right out of the box, the GPSMAP 478 comes preloaded with US marine detailed maps for the entire US coast, including Alaska and Hawaii. These maps are based on BlueChart g2 technology, so they layer smoothly and are integrated for easy panning, scrolling and zooming.

Go from Water to Land
When you're ready to drive home, take your 478 out of its marine mount and pop it into the automotive mount in your vehicle. Then press one button, and your 478 is ready to navigate you on the roads, with turn by turn directions and voice prompts that take you straight to your destination. The 478 is preloaded with detailed City Navigator maps for all of North America and contains over 6 million points of interest, including hotels, restaurants, gas stations, marinas, attractions and more.

Add Optional Weather, Audio and Sonar
See real-time weather on the 478's high-resolution TFT with the purchase of a GXM 30 XM antenna and a subscription to XM Satellite Weather and Radio services. View vital weather data, including NEXRAD radar, storm cells, wind speeds, surface temperatures, forecasts and more than a dozen other weather attributes, so you can enjoy the water without worrying about the weather. You can also subscribe to XM Satellite Radio to receive over 100 channels of commercial-free music, sports, news and talk radio.

For serious fishing, pair the 478 with the GSD™ 21 remote sounder, which offers 4,000 watts of power peak-to-peak (500 watts RMS) with a dual-frequency transducer (purchased separately).

Add More Marine Maps
The 478 accepts optional MapSource data cards, so you can add new maps without connecting to your computer. BlueChart g2 data cards let you view real, detailed aerial photos of harbors, marinas and other important marine landmarks and places, right on your chartplotter.
