Does anyone know if this will give you an alternate route to change to or you can specify not to use the highway? I drive to work on a highway full of construction and more often than not, there seems to be a wreck that has shut the highway down. If this will give me alternate back roads to take, I'm all over it.
Additionally to what JFreak said, you can also block the road ahead of you while driving. When you're on a street and you notice that there's a construction or an accident or whatever, you can block this road and Navigon will calculate an alternative route.
