There is no autorouting facility with the world map (other than straightline plots). It will of course still give lat and long position. and show general direction.
One "trick" I found in Albania, was not too zoom in to close. The world map is just as inaccurate as the base maps, and if your in too close it doesn't show your position accurately. From a wider angle it still gives a good indication of which way your heading and where the town that your heading for is in relation to you (assuming of course that your heading for a town)
