An apparatus and method for providing map information of varying resolution to a navigation device. In one embodiment, a position determining system is attached to a navigation device. The position determining system generates position information, such as location, of the navigation device. The position information is transmitted to a base station containing map information. Map information related to, for example, the location of the navigation device is then transmitted from the base station to the navigation device. The map information is displayed on a display of the navigation device. Therefore, the base station only transmits map information related to the position information of the navigation device.
