That is what I think also. I followed every direction of the Minn Kota tech. Replacing the control head is not difficult. No metal in proximity. Trolling motor was professionally installed by a reputable dealer. New batteries, bank charger, insulated wires, etc. GPS puck is fine and blue toothed to control head as the spot job works impeccably. Remote works great, software current, middle of the lake, easy access to satellites. Not sure what else?
