Our NMEA 2000 network updater provides the convenience of updating Garmin products and NMEA 2000 accessories that do not have a SD card slot.
Simply download a software update to an SD card and insert the card into the network updater. Using a simple "plug and play" installation, the network updater easily and temporarily connects to your NMEA 2000 network.
The NMEA 2000 network updater is not water resistant and should be removed after updating your NMEA 2000 network.
