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