I bought the Garmin Upper Midwest Fishing Guide preinstalled on a micro chip and started with it in a 62st, then moved it to a newer 64st. Now, I have their LakeVü map chip in my 64st and will probably be putting it into a 66st in the near future. I've never done the download and copy to a chip... it never seemed to be economically feasible. And, no, you can't copy the data from the chip to the unit and then remove... the chip needs to be installed to use the map data. But it can be moved around between units you might own.
