I currently have a HDS Live at the bow connected to AT1 and a HDI Transducer on the TM. This unit is currently not connected to the other units on the boat.

I also have a GEN 1 and GEN 3 at the console connected to each other via the original LSS1 box/transducer.

The GEN 1 is connected to a Transducer in the hull.

Can I disconnect the GEN 1 from the LSS 1 box so it only runs Reg Sonar and is not networked, plug the LSS1 Transducer into the back of the GEN3 then ethernet the GEN 3 to the Live to share waypoints as long as the GEN 3 is updated to 18.3 or whatever the latest download is?

The Live is running 25.1
