I also have this unit. I have not had any problems with the unit. I was concerned when purchasing mainly due to many having posted that there was screen visibility concerns. I am happy to report that I no issues viewing the screen. Of course it doesn't always choose the best route but neither has any of the 5 or 6 gps systems I have owned in the past. Obviously it is limited to its installed data so I purchased mine with life time map updates. I need to take the time to figure out how to adjust or modify the route it chooses. I would purchase this unit again.
