Color marine GPS :
(chart-plotter) Garmin
GPSMAP 478

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.
