Abstract
A motor vehicle information system having a programmable automotive tape recorder that can automatically deliver sequential prerecorded messages concerning road information and the like at predetermined intervals. An electromechanical adaptor connected to the odometer system of the vehicle provides pulses that are proportional to the distance traveled and these pulses are fed into a microprocessor which performs arithmetic and logic functions to drive a tape recorder with prerecorded messages. The system permits the distance data for programming the microprocessor and the related sequential messages to be stored directly on the tape such as a prerecorded casesette or for the distance data to be stored in the memory of the microprocessor with the sequential messages on the tape only.
