My winter project of upgrading my boat's electronics is just about to start. What I have are (2) Gen 2 non touch units and (1) Gen 3 unit. Also, I have an LSS1 module and Lss-1 transducer. I plan to mock up the units on the deck of my boat prior to the permanent install. For me, having the Gen 3 and a Gen 2 unit on the console and the other Gen 2 at the bow is best. I have found comments in other threads about networking Gen 3's to older units and the legacy mode???. The Gen 3 console unit will be used for DS/SS while the Gen 2 console unit will be mapping and 2D sonar. The bow Gen 2 will have 2D sonar and hopefully networked with ethernet to see SS, waypoints and mapping. With wanting to network all 3 units, I assume I will need to use the LSS1 module since the Gen 3 unit only has 2 ethernet ports. Does anyone see any issues or tips with this approach? I did see where the Gen 3 unit should have the version 7 update loaded with older Gen 2 units.
Any advice would be helpful as I'm in unchartered waters.
