The original StreetPilot with gray scale and no auto route planning is less than $500 everywhere I've seen it. It guides you based on a straight line between where you are and your destination. Not too useful if you're at one end of Golden Gate Park or Central Park and trying to get to the other end. You can manually enter a route. The unit will then give you turn-by-turn directions... if you're on track.

My sig line should give a clue as to why I don't want an in dash unit even at only $700
