I have a Helix 10 Gen 3 mega + DI. The Di and 2D transducer work great with no interference. Mega 360 as soon as I move the trolling motor pedal or use the trolling motor the interference is so bad it wipes out the screen. Help. I have a Ultrex 112.

Try changing the Noise Filter Setting’s. Mine had to be on 2 or 4 to get a clear picture and I had terrible interference if the noise filter was off or set to 1 or 3.

Wayne,
The cables are actually on top of the deck right now haven't routed them yet. Any suggestions..a lot of cable to place up under my bow panel.
Some route the cable along the motor power/steering cable BUT that is just inviting RFI. The best routing is along the mount to the deck so they are not close to each other.
Then you need to check the fuse in the top of the motor.
Also if you have an on-board battery charger that is connected to the trolling motor battery/s and the starting battery, disconnect the lead to the starting battery to see if RFI is getting to the unit through the charger.

So even without the battery charger not plugged in and charging. There can still be RFI from the charger?

Thank you for explaining that. Would a choke work on the cranking battery then?

I will be going out this weekend and taking my charger leads off to see if it helps with the MEGA 360 interference. I will report back guys. Interference is a frustrating thing to have to deal with..... where do you go on the helix G3 mega+ DI unit to find the noise filter? I only have the mega 360 transducer hooked to this unit.

I’m in the same “boat” your in with interference gonna look at some things today and see if I can sort it out. Gonna get a ziplock bag with water in it and put it around the transducer with the motor down in the driveway vs do things and have to take it on the water .

Can you buy this part on it's own or call HB and get one? In my case I have a CHO Mega DI+ unit that I plan on only using for the Mega 360 if I ever get it and I'm afraid I will also get interference and I'm thinking this might help.

I would think it would be provided IF you have an RFI issue. Since it is not included with a MEGA 360 there must not be a concern with it.
I don't think being afraid ahead of time would justify getting one. RFI is not a certainty. I did not install mine, actually sent it to someone to try and see if it would fix his RFI issue.
When I switched from a Motor Guide Tour to an Ultrex, I did not reinstall the TMC-1 trolling motor choke and didn't need to.
Extra measures were added to Minnkota trolling motors with MDI or MSI transducers due to the MEGA frequency and due to the MEGA frequency, that is why it is included with the trolling motor adapters.

Disconnecting the battery charger leads did not help my problem at all.
Next step is checking the fuse in the head and messing with the noise filter. (I forgot about that part while I was out this weekend)
I was able to use the 360 mega while sitting still and it is really impressive. Was able to see some lay downs in spawning pockets that held fish. I’ll be glad to not have interference though! I have all my cables ran down the man cable jacket. That will be my next step is to run my 360 cords another route.
Not sure if this will be of help to you but I also saw the interference you mentioned while on the water this weekend. I had been messing with settings to alleviate 2d cross talk and ended up causing tons of m360 interference that I’d never experienced before. I ended up restoring defaults on my helix and it cleared up my tm interference on my m360. Worth a try if you find yourself getting lost trying to adjust so many settings you lose track of what you’ve changed.
