The navigation system includes, among others, a searching unit and a scale changing unit to change the map scale to display the destination along with at least one map attribute when the vehicle is approaching the destination. The navigation system also includes a priority table to prioritize the map attributes and the searching unit searches the map attributes near the destination according to order in the priority table.
