nav4all seems like a -real- resource hog. and i hate that it won't let you see a map when you're moving.
Until googlemaps utilizes the hard keys for pan and zoom, i prefer MS Live Search. again, Live Search seems to have made a recent update, even tho it doesn't say "new client available," try getting the installer online and reinstalling it. I notice the traffic seems to cover a much wider area now, and the map seems to zoom a little better.
but the turn by turn directions are rudimentary at best, and it doesn't have quick info readily available like ETA and total miles. it's there, but not at a glance.
