My MG Xi5 is net worked through Lowrance HDS units. I think when the Lowrance HDS unit is used to tell the Xi5 go to a waypoint, the Xi5 uses the GPS coordinates it receives from the Lowrance unit and positions the trolling motor head over that point upon arrival. Make sure the Lowrance auto pilot setting is for the trolling motor to go into anchor mode on arrival at the waypoint.
I also find once the trolling motor stabilizes over the waypoint and the boat is pointing into the wind, I can use the jog feature on the remote control to move the boat so as to fish a brushpile from the side or back of the boat.
If we concentrated on the really important stuff in life,
there'd be a shortage of fishing poles
