Devices that can share supplemental map information and view data from a single radar or sonar module at the same time have a port labeled ETHERNET. Go to www.garmin.com or contact your local Garmin^® dealer to determine the appropriate type of devices for your needs.

When connecting this device to compatible ETHERNET devices, you should observe these considerations.

• This device is compatible only with other Garmin ETHERNET devices, and does not share data with Garmin Marine Network devices such as a GPSMAP^® 8000 series device.

• This device is not compatible with legacy Garmin sounder modules such as the GSD™ 26.

• If your device receives sonar data from a transducer connected to the SONAR port, it does not share the sonar data with other ETHERNET devices.

• A Garmin Marine Network cable must be used for all ETHERNET connections.

  • Third-party CAT5 cable and RJ45 connectors must not be used for ETHERNET connections.

  • Additional Garmin Marine Network cables and connectors are available from your Garmin dealer.

• If this device has a single ETHERNET port, you may need to use a Garmin network switch, such as a GMS™ 10 to connect a radar or sounder module to more than one ETHERNET device.

• If this device has both a RADAR port and an ETHERNET port, you can connect an ETHERNET device to either port.

• Some sounder modules, such as the GCV™ 10 have more than one ETHERNET port, and can connect to multiple ETHERNET devices without an additional network switch.
