I'm helping a friend upgrade his boat electronics, going from older Garmin units to two new Helix 12" graphs. He already has an Ultrex with iPilot Link. He'll be putting an MSI+ unit on the console and a MDI+ unit on the bow. Do the G4N units still use the same Ethernet connections or is everything now NMEA 2000? He really only wants the Ultrex and the two graphs linked together, but I'm guessing in the future he'll want M360 and MEGA Live too - haha!
Just want to make sure we order everything needed the first time.
Thanks!
