I have new Helix 12 Chirp units connected via Ethernet with only one transducer - after a few minutes of running the sonar on the unit sharing the transducer I get a message "lost 2d source"...does the same with SI and DI and reverts to the map view. I can go back to sonar and after a few minutes it repeats the same error message and always goes back to the map view.
anyone have this issue? Suggestions?
