User Reviews

Used mass511 for the first time today trying to get back home to NH and the info I received was accurate and timely. I was able to find the quickest route. I liked that it has my location so I can see exactly where I am at any time. (I was a passenger and not driving.) I didn't try the voice mode yet so I don't know how well that works. The only down side... I couldn't access any of the cameras. Got a message each time saying that they were temporarily unable to be viewed.
