Jackal24,

The box says global, but the MMC card says America's.


Weird. Well, if the card says Americas, then you'll get less accurate
terrain outside the Americas. You might even get less accurate terrain
in South America, but that's something for Lowrance support to answer.
Where did you look? Do you see terrain vanishing everywhere below 30
nm? Have you checked the "Map Categories Drawn..." part of the menu?
