I sent mine back and they said it checked out fine but he still put a new board and something else and said that I must have a voltage problem,brand new boat and batteries.I checked voltage and replaced trolling plug and still anchor lock is only functional if you tie the anchor rope around the trolling motor and advanced auto pilot is useless.Very disappointed and done with minkota if they cant fix this to function AS IT SHOULD FOR A 1600 DOLLAR MOTOR.
