ABSTRACT:
This invention discloses a system whereby a recorded magnetic tape is played on a tape recorder presenting information in audio format to the driver and passengers of vehicles. The tape recorder may be automatically controlled so that particular descriptive, informative, or instructional passages are played at appropriate locations along a determined route. The recording is correlated to distance traveled by a device which senses the operation of the cable which drives the vehicle odometer, and by corrective information regarding tire diameter and cable to wheel rotation ratio. The correlation is correctable to correspond to an external reference system, specifically mileage markers along interstate or other highways which have standard mileage markers, thus insuring a high degree of continuous synchronization between the location of the vehicle and the particular passage played.
