Thanks Ward,I appreciate it. I did do the overlay and have the water temp data set to show up on the Map, sonar, and structure scan. Its just showing up as dotted lines. Im probably going to bite the bullet and sit down with my manual tonight and pick through it to see what I can find. I believe it is something along the lines of the temperature sending unit not being recognized by the new unit. I believe its not getting the data. My Eyra has the Bass Cat installed temperature sensor on the transom which I think is a standard feature since my old classic had it as well. I am assuming this needs to be setup in the unit to receive the data???
