Go straight from the box to your boat to your vehicle with the GARMIN GPSMAP 478 Portable Navigator (010-00543-00). Along with its counterpart, the GPSMAP 478, this combination color chartplotter and street navigator comes preloaded with detailed marine maps and detailed street maps, so you can find your way anywhere.
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.
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 GPSMAP 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.
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).
The 478 Portable Navigator 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.
