I bought a boat with a gn3 and gn4 helix di units. They are networked now, but I am planning on putting my gn1 12 helix with SI on the console and mounting my SI tranducer on my jackplate and then moving both of the newer units to my bow and getting a 360 for it. My question is will my gn1 Helix 12 network to share mapping and waypoints with the 2 newer units on the bow? Thanks.
