Haha, I'm glad to hear someone else bought a Humminbird, but this is a quick fix. Go to your chartplotter screen, hit "menu" and go down to "map data.". Select it and go to "map datum" I believe, and hit the drop bar (should be preset on Lowrance map) and select Navionics. Then, go over to "Navionics Map Choice," and open the dropbar. Here, you will select whatever state you are in (I.e. KY); you are done, unless you go into another state, like crossing into TN from KY on Dale, KY, and Barkley Lakes. PM me if you are still having issues. I work with various fishfinders all the time at BPS.
