I have a Lowrance LCX 27c and have an issue. It's wired up properly but when the main power switch of the boat is turned on, the Lowrance automatically turns on with pressing the power button. Also, it doesn't recognize the GPS Puck. Other than that the unit works great. I tried plugging it into my front connectors at my trolling motor where my other finder is and I get the same thing. Has anyone experienced this kind of issue before? Thanks
