When networked together via Ethernet, HELIX and SOLIX models will share:
Waypoints
i-Pilot Link information and control
360 Imaging (note that HELIX and SOLIX will not share MEGA 360 with each other)
Humminbird CHIRP radar
Bluetooth Talon control**
NMEA 2000 network information***
*Depending on technology built into each networked fish finder, some sonar images may not be shared if unable to be supported by your unit’s software. Ensure that you are running the latest software by finding updates here: https://www.humminbird.com/support/software-updates
See full compatibility of networking and sonar information here: https://www.humminbird.com/support/faqs/EthernetSonarSharing
**If both HELIX and SOLIX are on the network and need control of Bluetooth TALONs then at least one SOLIX and one HELIX G2N/G3N must be paired to the Bluetooth TALON at the same time.
***If both HELIX and SOLIX are on the network and need to view NMEA 2000 data, then at least one SOLIX and one HELIX G2N/G3N must be connected to the NMEA 2000 network. The HELIX G2N/G3N would be connected via the AS ETH NMEA2K NMEA 2000 Gateway.
