Probably a silly question. I just got a Low Hot Spots card for my XOG Lowrance. It does accept this card according to Lowrance. I stuck it in the card slot now should I see something or do I have to be on the water to see something? I guess what I am asking is how do I know the card is working? I don't see anything asking for lake selection or is that an auto function.The XOG is a unit for the auto and for marine use.
