Where are you pulling 360 power from? Where are you pulling Helix power from?
Both the 360 and Helix run off the cranking battery

Do you have an on board charger hooked to cranking and trolling batteries?
Yes sirQuote:

Try unhooking your charger from the cranking batteries. Sometimes that can be a path for interference. If that doesn't work, make sure your Ethernet chord from the 360 is well isolated from the trolling motor power chords.
First want to say I appreciate you helping me out.Quote:

But surely there is someway to stop the interference with the charger connected??

On my boat.I didn't have interference from the original charger.my charger went bad.I replaced it with another name brand charger.I got interference then.this charger has in line fuses,that I remove while out on the water.
Same reason I use a two bank on the trolling batteries only. Figure motor battery gets charged enough while running. If in doubt, I charge before fishing with a separate charger.
I also have a dual bank charger for TM batteries and separate off-boat charger for cranking battery. This year I will install a charger for the cranking battery on the boat.
You just need this choke from humminbird wired between the charger and ignition battery. It eliminates rfi feed back from the maximizer in the trolling motor. The new mega di transducer comes with it. Also if you have a ultrex, change the 3a fuze in the head to a 5a.

You can install isolation switches between your charger and the batteries to remove it from the circuit.
This is the choke that humminbird make to isolate from the charger and it works. I dont know the part number as it came with mega di transducer. Its not the one on amazon or HB website. HB was very helpful with our 360 rfi issues. May give them a call.Attachment 290140
