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

I imagine that the power button is stuck.  There may not be a fix.  Do you have an external gps puck?  If so then check your connections on the network.

I thought as well about the power button, but you can turn the unit when you press the power button, but you can't turn it back on unless you turn the main power switch off and then back on. The GPS puck is external and I've tried the connections and everything looks fine.
