    This is definitely interesting. This definitely sounds like trolling motor RFI, but it could be coming from the Pulse Modulation that Minn Kota uses for speed control. If the RFI goes away when the trolling motor is at 100%, then it is probably the Pulse Modulation that is causing the RFI and not the motor itself.

    Please try the 100% speed test to see if the RFI goes away and let us know.

    Actually, when I use 100% I get interference on my Mega Live for sure. On spot lock this interference happens but not as bad. It usually happens when the actual trolling motor is steering. On a side note, when I first installed the Quest I removed the Y cable and connected the built in 2D Quest transducer to my Mega Live unit and the Mega 360 to my other unit. No cross talk or interference on those two units but with the default 2D transducer selected I got horrible cross talk on my console 2D unless I selected a different transducer. I also started getting the pulse rings from my Mega 360 again on my Mega Live so that is why I went back to the Y cable.

    I guess I could not use the 2D and just connect my Mega 360 but I like the 2D next to my Mega Live and I'm afraid I will start getting those frigging pulse rings on Mega Live again. It's so frustrating because before the last update and trolling motor change everything worked perfect. Now I have my Mega Live finally working again but my Mega 360 and 2D are not.
