An electronic tour guide overcomes the monotony of an automobile trip. The system includes a GPS receiver, a computer, and a database of pre-recorded information. These components may be contained in one housing, and may be permanently installed in a vehicle. The database contains information pertaining to various geographical regions. The computer receives a signal from the GPS indicating the position of the vehicle. The computer then retrieves information from the database, the retrieved information corresponding to the position determined by the GPS receiver. The information is presented to the traveler, either on a video display or through an audio playback unit. The system can therefore provide information on the history, geography, and/or culture, relating to the region through which the vehicle is traveling. The information can be modified to include specific reference to points of interest with respect to the instantaneous position and orientation of the vehicle.
