Take one GPS add two incautious people get this: Mail I had to fight off the urge to tag those folks with something other than incautious.

I don't know about other GPS navigation units, but my Garmin LM3550 has a setting for how much detail I want to show on it's maps and whether I want flat mode or terrain mode. I have these set to maximum detail and terrain mode at all times.
With these two settings, you can zoom in and out to see all roads, canyons, mountains, lakes, rivers, cities, etc., around a route. Doing this, you can determine how much trouble you might be getting into by planning on, or staying on, a particular route - and then make adjustments accordingly.
At planning time, our Garmin also allows choice of two routes for every destination. Once started on a route, it also has a Detour icon that can be pressed at any time to have it look for a different way to your destination other than by using your current route from where you're currently at.
If you're going to use only satellite based or only cell tower based navigation instruments, you have to understand all their features, strengths, limitations, and weaknesses ... or pull out a paper map and/or Pay the Piper.
