There’s a lot of missing info here… are you trying to run ipilot link? If so, you have to have an ipilot link terrova, and a helix g2n with link compatibility.

I’m fairly sure that the ice units were not sold with GxN head units, because, why would you want to network portable units???
Also, from the link above, 5GxN units are not link compatible. Which, I think a lot of the ice kits were 5″ units.
Life uninc4709 said, if you’re trying to just hook up sonar, you’ll just need the correct adapter to connect the tm ducer to the bird unit.
