Garmin 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 temporarily ¹ connects to your NMEA 2000 network.
