• the radio control circuit 57 supplies the corresponding data to a tuning circuit 58 controlling the tuner 54.
• the RDS decoder 63 supplies the RDS and TMC data taken from the output signal of the intermediate frequency stage 55 and a clock signal to the control circuit 64.
• the control circuit 64 which processes RDS-TMC data like the control circuit 7 from FIG.
• the speech synthesis circuit 65 supplies TMC Data to the card reading device 66 and forms control data from the data received from the card reading device 66 and further from the memory 68 (data in spelling and spelling), which is supplied to the speech synthesis circuit 65.
• the speech synthesis circuit 65 generates speech synthesized from the control data, which speech is supplied to the audio amplifier 50 via the radio control circuit 57.
• the control circuit 64 optionally forms a traffic report in writing from the control data, which is fed to the display device 61 via the radio control circuit 57.
