if when you bought your unit you could of paid $200 less for a model without ethernet would you have done it. if yes i have a proposition. i just bought an ipilot link motor which connects to depth finder, but i have the older 798 without ethernet. there is no other difference between the two models. so im offering my head unit and $200 for your 798hd head unit, no transducer, base or wires exchanged.
