Abstract
Abstract A portable terminal and an on-vehicle device are combined such that effective navigation can be provided. The portable terminal provided with communication function is connected with the on-vehicle information processing device when placed on a cradle. The portable terminal transmits a destination to an information center, and shows obtained route data on a display while transmitting the route data to the on-vehicle device which outputs guidance speech from a speaker. On arriving near the destination, the on-vehicle information processing device provides the portable terminal with map data for the vicinity of the destination. A user can remove the portable terminal from the cradle and reach the destination while viewing a map shown on the display of the portable terminal.
