Just the amount of space that's on it.

The class determines the right speed. Class 8 being faster than class 4

i see. man you guys are helpful. so i just put my sand disk into the computer and download the stuff on there and then put it in my 997? i seen ther was a spot for 2 cards in it. on the front of the unit. are those for 1 navionics and 1 sand disk?

yes one for navionics/lakemaster the other for sd(it doesnt have to be san disk, that s just the one humminbird recommends) doesnt matter which card slot either although one card slot will let that card stick out just a little bit farther than the other
