I'm having an issue with my Mega-Live transducer.
Sometimes it connects to my sonar units, and sometimes it doesn't. When it does connect, sometimes it works, sometimes it doesn't. It's frustrating. I do get a diagonal line, like hard bottom, across the screen when not in landscape mode.

My set-up.
Helix 9 GN4 MDI, bow, with M360 and MDI transducers attached to it.
Helix 9 GN4 MSI, console, with MSi transducer connected to it.
Minn-Kota Terrova I-Pilot Link with MDI transducer built in.
Mega-Live.
Ethernet port- terrova, both Helix 9, Mega-Live are connected via the port.

Do I need a seperate sonar unit for Mega-Live?
What am I missing?
