Hi,
If you'ld like an abundance of information on GPS units, GPS Information, is a good start. All the popular brands of handhelds/portables/OEMs and retrofitted units appear to use NavTech (now NavTeQ) mapping software. This is vector-based which allows "overlaying" of data sets to build the map seen on the screen, so your decision on which to buy will boil down to the one most user-friendly for you to use. BTW, many do not give detailed mapping of roads in rural areas. Fugawi makes a software product that allows interpretation of maps (both raster and vector) onto their product for use on a laptop.
