Dumb question but I Just can't find the answer on the Minn Kota web site
I have a Terrova with i-pilot factory installed and am looking at several Humminbird GPS/Combo's
I realize I will need interconnection cables between the two

How does i-pilot Link fit into the picture when I have i-pilot in the motor already?
Do i-pilot and i-pilot link require different hardware to operate?

Thanks for the help
