IPilot Link is compatible with any generation HELIX 8 and larger (and some HELIX 7 if it has an “N” in the model name) ...
HELIX 8 and larger generation 1 can share waypoints, accessories and Sonar with your current core unit ...
HELIX 8 and larger G2N (and helix 7 G2N) and newer can share waypoints and accessories (no Sonar sharing)..
