Useful GPS

Garmin makes a DVD that you can purchase with all the 3D topo maps you could possibly need.

Their DVD is packed full with every bit of information needed to plot a trip. The DVD allows easy transfer of detailed 3D topographic maps from your PC to a "compatible" Garmin GPS unit.

National Geographic has come out with an awesome Mapping Software. You can do some exploring before you even leave.

Once you plot a course, the software lets you "fly" over your route using 3D magic.

Introduction
Our introduction to GPS was when we bought our laptop. We had an old version of Microsoft Streets and Trips on our desktop computer, and we were quite familiar with this application. We noticed it could be used with GPS, so we went to a local computer store and purchased an updated version of Streets and Trips which came with an external GPS antenna. You simply plug it into your USB port and you are ready to go.

After we had our Microsoft Streets and Trips with GPS, setup on our laptop, we went to visit some friends in Eastern Connecticut. When we showed them what we had, they wanted some mapping software for their laptop too.

We were introduced to Microsoft Streets and Trips with GPS not long after we got our laptop computer.
Somehow we found a flyer from Comp USA and they were runnng a special on the Streets and Trips, which included a GPS.
