Have a G3N Helix 12 SI connected to a G3N Helix 10 DI. Fished in the rain today and now I’m getting a message on my 10 that says “SI Sonar Source lost” and asks to confirm turning it off. Even though I hit YES multiple times, it keeps coming back. I also noticed waypoints from the 10 aren’t making back to the 12, but donfrom the 12 to the 10. It was suggested to me it might be a bad Ethernet cable. Any thoughts?
