Please back up your user data before applying the update.
The use of an SD card that contains mapping data is not recommended for this update.

Click on 'Download' and choose to save the file to your computer.
Once the download is complete, copy the zip file to your SD card.
Double click the zip file and select unzip to extract the files to the SD card. The 'Garmin' folder should be the top folder on the SD card.
Power on the device and make sure all attached network devices are powered on as well.
Insert the card into the card slot of your primary device. Select 'Update Software' in the window that automatically displays. If you do not have a primary device with a card slot, please see your dealer or attempt to use the ActiveCaptain app to update software.
After the update completes, all Garmin Marine Network devices and NMEA 2000 sensors will have the latest software. This ensures all of the devices will be able to communicate with each other.

Note: If you have additional chartplotters connected to NMEA 2000 and not the Garmin Marine Network, you will have to independently update each chartplotter. After the update of the Garmin Marine Network completes, insert the update card into each NMEA 2000 chartplotter.
