Humminbird Greg again

OK, if Humminbird depth finders are Navionics compatable, and Lowrance is Navionics compatable, can a Humminbird finder (597) read the same Lowrance Hot Spots maps that my Ifinder GPS uses? I am tired of having to buy new maps all the time.

I don't care of the GPS coordinates that I have saved will transfer or not, I just want to use the Hot Spots maps that I already have if I can.

No I do not think that the Lowrance Hot Spots mapping card will work in your Humminbird 597 unit. I suspect that the Hot Spots maps have a different format or file extension than the Navionics mapping cards do.

Thanks, it was worth a shot anyway.
