Got similar setup with a 10 and 8. Jigman pretty much nailed it on setup. Agree with Jigman–I have a transducer on my trollin motor. You will need to hook eathernet to bow unit as mentioned. If I remember right you need to source that (local) transducer instead of network transducer. Also, setup is a PITA to transfer waypoints from console to bow. I think with ethernet they might only transfer at power up, with N2K they update frequently. When you get that licked, keep in mind the distance between he units internal antennas will throw you off. Also, on Gen 1 units the internal antenna only updates @ 1HZ, not sure bout GEN 2. If you install Lowrance antenna near your SS transducer and source that rascal N2k you get 5hz update on GPS. Gives you a consistant boat position to waypoint. Makes for a much improved boat position update on the chart page if your scootin down the lake. Also, seems like when the air is thick with moisture I get a slow update on position. You got a great setup. Leave your rods at home and take your Lowrance operations guide to the lake and learn to use those Lowrance units. One last tip, if you are gonna pull the ethernet cable, keep the thing away from any trolling motor wires or anything else that will induce noise. BCB did my install complete with Ethernet cable, but that was in the build instructions. Great install!!!!
