The pre-loaded chart package provides wide ranging coverage that includes both U.S. mainland coasts from Canada to Mexico as well as the Bahamas, Puerto Rico, Hawaii, Guam, and the Great Lakes. Auto Guidance and full 3D chart views are available when an optional Visions card is installed.
All of the compact Garmin 400-series chartplotters measure 5-inches high by 5.7-inches wide and just under 3-inches deep. They are available in several configurations.
The middle number in the three digit model designation identifies the cartography coverage area, 5 is UK/Australia, 4 is U.S. coastal, 3 is U.S. inland lakes, 2 is base map only.
All the latest versions in this series, designated with 4×1 model numbers, are capable of using a single Garmin BlueChart g2 Vision card, interfacing with an optional XM weather and radio receiver, and can connect to your vessels NMEA2000 network.

The pre-loaded cartgraphy package shows good detail on the chart page.
If you will be mounting this unit inside a wheelhouse or under a T-top the best performance will be attained by installing an external GPS sensor with a clear unobstructed sky view.
This Garmin GPS chartplotter can interface with other compatible marine electronics using one of its two NMEA0183 ports or via connection to a NMEA2000 network.
Either of the two NMEA0183 ports can be used to communicate with devices like a V
