Garmin GPSMAP 8416 16 Chartplotter w/Worldwide Basemap

The Garmin GPSMAP 8416 is a 16-inch Full HD chartplotter with a 1000-nit IPS touchscreen, Worldwide Basemap, and external network sonar support through GSD or GCV modules. NMEA 2000, NMEA 0183, J1939, two Garmin Marine Network ports, HDMI input/output, USB-C, WiFi, Bluetooth, and ANT+ support a large connected Garmin installation.

Who Is This For?

This model suits offshore fishing boats, cruisers, commercial vessels, and multi-display helms that need a large Garmin chartplotter but plan to use external sonar modules. Its Full HD display provides room for charts, radar, video, and engine information.

It is not ideal for a buyer seeking an all-in-one fishfinder, because sonar requires compatible GSD or GCV network modules. The Worldwide Basemap also does not provide detailed regional chart coverage without additional chart data.

Warranty & Support

Garmin provides a 2-year standard warranty. The supplied specifications do not state warranty exclusions or service procedures.

The GPSMAP 8416 is the large Garmin chartplotter option for installations using external network sonar, offering more screen area than the 9-inch GPSMAP 923 and broader video connections. Its trade-off is the lack of built-in sonar and the Worldwide Basemap. Choose it for a planned Garmin glass helm with separate GSD or GCV modules, not for a self-contained fishfinder package.
