Hope, I think that you should be able to fit about 5 or so maps onto a 1 GB CompactFlash card. This will depend on the size of the map. For example, California is twice as large as Florida. If you had a set of maps that you wanted to load in mind, I or someone on the list can figure out if they will fit or not.

I'm not very good at math, so I'm wondering approximately how many states can fit on a 1 gb cf card? I'm going to make a trip to Florida, and I'm wondering if I'm going to be able to get all of the east coast onto that sized card. Hope and Beignet
