I thought i could use the Mapquest website forever before buying my Garmin GPS.It tells you the street names and which street you have to make a turn.It tells you if there is heavy traffic on the road  and it even tells you if there is a better route available .The Garmin GPS always calculates the estimated arrival time and  it 99% accurate.Forget MApquest or other  MAp sites .Some Gps touch screen dont work after some time but we have this GPS for quite a while now and it works smoothly.
