I had a power drive with the updated I pilot head added on after I had bought the motor. It works pretty well, and I didn’t have issues with it. I bought it mainly to have the spotlock ability for that motor.
My current boat has a Terrova with I-pilot and the gps puck. I have to say having the jog feature it very nice. The Terrova replaced the same model Terrova that was on the boat when I bought it but 11 years newer. The GPS, and software the newer motors use is definitely an improvement over the early ones.
