GPS with Campground Navigator

I tried my GPS with a friend's Good Sam Campground Navigator. It gave the initial position when I started the tracking but then did not update the position. I could see the satellite data changing in the box on the lower right so it was getting to the program. I also tried the GPS with S&T and it worked correctly. Does anyone use Campground Navigator with a GPS and does it work right? Any ideas?

tenbear, at least for testing purposes I would suggest to put Franson GPS Gate between your GPS receiver and Good Sam Campground Navigator. Often time GPS Gate solves these sorts of issues.
