Navionics prob

I got my new Premium Hotmaps south 08 yesterday in the mail. well, I opened it up and it said it was a plug and play type deal, so I go out to the boat, and pluged it in, and there are no MS lakes on it....What gives? bad card?

I said, well, mayby it ain't compatable with my HB 595c, so I called a buddy of mine, and went and loaded it into his Lorance 26 HD, and it didn't work in his either.

I'm pretty upset, hope I just got a bad one....

Huh. You said no Ms lakes - does it do anything (any lakes)?

That's the one I've got, just stuck it in and it worked.

If it shows Al and Ar and LA, but not Ms. I think you have a bad card.
