Function requirements:
When circuit 15R is active, the functions of the radio and navigation unit are available. If circuit 15R has not been activated, then the MOST subscribers are activated when the radio and navigation unit is switched on. In this case, control using the multifunction steering wheel is not possible.
Radio reception
2 radio tuners that can be controlled via the controller unit are integrated in the radio and navigation unit.
Operation via the interface is generated by the radio and navigation unit and displayed on the screen.
The audio signals are amplified by the radio and navigation unit and then output via the vehicle speakers.
With code (810) Sound system, the audio signals are routed to the amplifier for sound system, amplified there, and output over the vehicle speakers.
