I found a great website that has ooldles of Points Of Interest (Truck
Stops) and more for the GPS, I have a Garmin C 550 that I downloaded the POI
downloader from Garmins' website and used the Pilot Travel Centers listed on the
POI file to upload to my GPS, they showed up great, now those that have a GPS
can find and upload to their GPS convenient Truck Stop and many other travel
related helping directions
