Had to come back to this...I forgot something... There is a setting on the automotive GPSs (not all, but some) that lets it track your path. You can then save that route. I do not know if this would work if you were traveling on backroads.
Some of the handheld GPSs that hikers use might be a better option. Also...there may be specific maps available for your needs but you would need to know which GPS you intend to use first. Some of my nerdier friends do Geocaching and use these types of units.
I would check the REI website as they are one of the more reputable outdoorsy retailers out there (in my neck of the woods) then take what you learn and purchase accordingly.
