The first time I used it to drive to out of state because I heard it will inform you of road conditions, such as unplowed roads, icy roads etc. As soon as a snow storm hit while I was on the hwy, it told me to exit the hwy. Go over a bridge. It then took me to a neighborhood in the woods as it was getting dark (The opposite direction of the hwy and where I was SUPPOSED to be going). It took me through unplowed, fresh snow, 2 inches deep, then uphill, & around in circles until I was lost.
