A buddy told me he turned his console unit completely off & it cured his flash problems. He tried standby but didn't work so turned it off & has worked good since he says. By the looks you'd think it was trying to have 360 & live on both at the same time.
Trouble is,,interferance can come from anywhere. It might be in wiring, trolling motor, a transducer wired to motor, mega 360, wires too close to trolling motor power wires, on board chargers. You just have to search each imaginary possibility out sometimes and can be a real pain in the arse. I have no flashes when running mega 360 and Mega Live until I am in 8’ or less depth of water on a hard bottom. And I can live with it as it’s not extremely bad then.
Thanks for all the help. Will try moving some qireing around next time out. I have it on a separate pole and stand alone battery. But it is close to TM power wire.
Ok guys , I feel like I'm beating a dead horse with these questions. I have done everything to get this interference out of this unit. I have adjusted every way I can. I moved unit in the boat, unhooked trolling motor. I even put unit on old pontoon in my pond with no wiring or outboard, no trolling motor either. Same results. Is it time to contact HB?
Apoligize ahead of time but better yet contact Garmin. Far superior. YMMV Scott
