NMEA 2000® Network Updater
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 temporarily¹ connects to your NMEA 2000 network.
¹The NMEA 2000 network updater is not waterproof and should be removed after updating your NMEA 2000 network.
