I think that the original poster was trying to say the following. When you buy the GPS, no course maps are included. You pay a $10 "activation fee" and then you can download thousands of course maps. However, you can only keep 10 at a time on the gps. Therefore, it would be great to download 50 or so, keep them on the hard drive and then flip them back and forth between the pc and the gps. This would save paying the activation fee (i.e. download fee) every year.
