Garmin Marine Network Considerations
This device connects to Garmin Marine Network devices to
share radar data with compatible devices on the network. When
connecting to a Garmin Marine Network device, observe these
considerations.
• A Garmin Marine Network cable must be used for all Garmin
Marine Network connections.
◦ Third-party CAT5 cable and RJ45 connectors must not be
used for Garmin Marine Network connections.
◦ Additional Garmin Marine Network cables and connectors
are available from your Garmin dealer.
• Although it is not recommended, you can use a field-
installable connector to create a custom-length Garmin
Marine Network cable if necessary. Follow the directions
provided with the connector.
