I use Toposcout and it will allow me to set up GPS points and routes. The newer Terrian Navagator has the same features and more for a very reasonable $99.95 for each state or region. I think that Terrain Navagator is by far the best value forthe money. Here is the link:

Here are some links to shareware mapping products you can check out. I am no familiar with all of their features.
