We now have the On-the-Road combined with the Off-Road Systems.
Traditional Handheld GPS Systems like the Garmin eTrex remain very popular, as do the traditional On-the-Road GPS Systems like the Garmin Nuvi.
Now you can get the full functionality for Off-Road and On-the-Road in the same unit.
A relevant example is a System that has the traditional On-the-Road highway mapping and the associated features, and also has topographical mapping and features for use Off-Road.
This type of System would commonly be used by users that frequently find themselves in both environments and do not want to have two seperate systems.
With this unit they can navigate on the highway to the Off-Road area, and then use the Off-Road capabilities when they leave the highway.
Sample users would include workers in undeveloped areas, 4 wheelers, and even trail riders.
It is even Geocaching Friendly
