NMEA 2000®

NMEA 2000 is a combined data and electrical network that enables communication between marine electronic equipment (such as chartplotters) and GPS devices.

The NMEA 2000 network supports a multiple-talker, multiple-listener data network, which is an improvement over the NMEA 0183 network.

For a product to become NMEA 2000-certified, it must undergo a rigorous certification process established by NMEA (National Marine Electronics Association). All NMEA 2000-certified Garmin marine products offer a true "plug-and-play" installation system for adding devices to your NMEA 2000 network.
