While I still think that the ability to read a map and use a compass is preferable to using to the new-fangled electronic devices, I have decided to purchase a GPS unit. Being conservative (translate that as "cheap" ), I would like to find a GPS unit that can be used in the Subaru, and then, after arriving at my hiking destination, can be removed and used on the trail. Features should include the capacity to use the auto power supply and be able to run independently on batteries, good battery life, decent memory, etc., and a reasonable price.
Any suggestions as to what to look for?
