The GPS device picks up location data from satellites in Geostationary orbit, from these it can calculate yout position on the globe.Originally Posted by icet
Costs - varies, I guess a GPS unit could be anywhere from say $40 - $200, I use a Deluo GPS whicg runs arounf $80.
There is no monthly fee to pickup GPS signals.
Software - Destinator, Routis, MapPoint, CoPilot, StretFinder, TomTom - there is a lot, some better than others depending on region, device and personal preference.

Destinator 3 seems to be one of the best at the moment, but you have to check the map coverage. Theres also alturion, mapsonic, route 66, routis and and some others...some only cover USA or europe.
