So can a gen 1 Helix SI link to an Ipilot terrova with link? I am getting mixed answers. I just want to be able to select a waypoint from the screen on the Helix and go to it and have the trolling motor drive me there. Also wondering if a Gen 1 Helix SI can share waypoints with a 859ci Hd? I don't care about seeing sonar on the others screen, I just want to be able to see the waypoints on both and when I save a point on either graph I want it to be saved on both. I understand I wont be able to share mapping but hopefully waypoints will work.
