The included points of interest make it easy for the driver to find the services he needs. The points of interest database will make the WorldNav a truck driver’s best friend, locating places to rest, fuel up and eat.
  • Showing Restricted Roads Roads are color coded, making it easy to determine the best route and what routes you need to or should try to avoid. When your system is in the Map mode you will see your road types with the colors listed below:
    • Gray = Residential
    • Yellow = County or state
    • Orange = Highway
    • Green = State Preferred Truck Route

This unit has a tendency to lock up. The screen goes black and you have to reset it and then enter the route again, it’s very annoying. It works fine otherwise.
