Feel I know what I need to order but trying to prevent need for return.
Buying:
A) 547sx no/trans. B). Garmin network cable JR45. C) minnkota US2-14
Connecting 547sx to network ( waypoints and sonar) to my 840sx. Connecting 547sx to Minnkota Terrova.
Ordering on line, could call but have found this sight very dependable.
Thanks
