I have a friend looking for a GPS to be used primarily for driving
directions to addresses mounted in a car but also able to use portable for
geocaching.  Does anyone know of a GPS for cars that can be used to enter
addresses and get directions and also allows input of waypoints for
geocaching?
 
Also, have a friend interested in a GPS around $200 for geocaching only.
 
Any recommendations for these two?
