I have mine linked with an ethernet cable if that is what you are talking about. Jimmy did the setup on mine. He can probably give you some tips. @Jimmy RodandReel
@Curt I have had my interlink for years and it has been great! I have even swapped out units and as soon as you plug in it downloads everything to the new unit.-Mitz

curt , I used to have a 797 with side image and a 997 with side image. I had them configured with an interlink. I had the 997 on the console and the 797 on the bow. I mounted the interlink up under the console on the rear wall of the front rod locker . It was up under the helm. It worked well. On my units each had an option to select to participate in the network. When I selected each of them to participate fully it shared waypoints with both units. It was a nice setup and once you get it up you will like it.
