The Garmin Nuvi680 is a great product and does what I expected from a high end GPS system, fast and does the job perfectly. The screen is perfect with the brightness, you don’t have to try very hard to see it clearly. Of course there are always little bits of problems in terms of route selection, such as when there’s construction or something, but things like that can’t be expected anyways. I’ve already had some pretty good results with the nuvi680 from Garmin, which in my opinion is the best GPS company out there. I tried to take some turns early or at the wrong places and this performs perfectly in recalculating a new route to my destination. Using it can’t be any easier either. I think this would be a very useful add on to anyone’s car.
