So I just got everything installed today and I was turning the unit off and on messing with the settings a little from what others have suggested and sometimes the Structure Scan page would show " NO SOURCE". If I shut off the unit and turn it back on it's about 50/50 if the structure scan is going to come on. I've got the yellow wires together to turn on the structure scan box..... Any thoughts on this? Is it because it's out of the water?
