The lightweight, portable unit comes pre-loaded with detailed US marine maps for the entire US coast, including Alaska and Hawaii, based on BlueChart g2 technology, so they layer smoothly and are integrated for easy viewing; it also includes City Navigator maps for all of North America, including over 6 million points of interest; plus tide tables, sun/moon data, and a hunting/fishing calendar. Find anything, anywhere.

The unit is also compatible with Garmin sonar and DSC for precision marine navigation. Pair the unit with the powerful GSD 21 remote sounder (sold separately) for high-tech fishing! The GPSMAP 478 is XM-radio ready (separate subscription required), so you can enjoy XM radio programming and listen to WX weather reports on your boat or on the road.
