I guess I am more old school than I thought. For my needs a garmin nuvi to get me into the general area, a gazetteer (Delorme or Benchmark), a compass for backup and maybe a geology guidebook or two are all I ever use, except for eyes and the feel of the road or trail. Generally I try not to be too dependent on GPS unless I am in a city -- where it is very useful. Different experience and expectations I suppose.

Here is my first GPS unit:
