Abstract
A radio station tuning system enables a radio receiver installed in a vehicle to be automatically tuned to a radio station offering a desired program. In the system, a controller receives data recognized by a speech recognizing unit and a current position of the vehicle detected by a navigation unit, provides the data to a communication unit, turns a radio receiver on or off, and tunes the radio receiver to a desired radio station. The communication unit sends data to a base station data via a vehicle telephone line. Receiving the data, the base station has access to its data base storing program data (e.g. broadcasting time, frequencies and so on), retrieves desired data, and transmits them to the vehicle. The controller automatically tunes the radio receiver to the desired radio station on the basis of the received data.
