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.
