GPS is not the same as (in-car) navigation. "GPS" is purely a positioning system. You can use it to figure out where you are. A navigation system (like TomTom) uses the GPS position along with a digital map to determine where you are and calculate the quickest/shortest route to a given destination.

The earth is like a tiny grain of sand, only much, much heavier.
