New Mega 360 user so im still learning. My problem is that 360 shows nothing (black screen) when I switch from 455 to mega freq. It works great in 455. I have the mega 360 hooked up to a dedicated Helix 15 DI G4N+, no other transducers run thru this unit. I have clean power (10ga marine wire) run from each bow unit to battery.
Current updates, Mega 360 transducer selected, factory default reset run several times. I've even tried powering down all other units in the boat, including ethernet hub, and running only the Mega 360 and dedicated Helix 15 DI.....same result.
Any thought?
Could this possibly be a low voltage issue? Would the 455khz still work fine if this were the problem?
TIA!
