Role of main components
The radio computer manages the various multimedia system functions according to user requests and transmits
audio data to the vehicle via the speakers.
The radio uses an amplified aerial system to improve radio reception.
The aerial amplifier is incorporated into the roof aerial.
The speakers reproduce the radio system's sound inside the vehicle.
The microphone allows the telephone to be used in hands-free mode via a Bluetooth connection.
The tweeters reproduce the high-frequency sounds of the radio system.
The multimedia interface unit (Display or Multimedia connection unit) receives various signals from the vehicle CAN
(speed, status of exterior lights) and retransmits them for the radio via the Multimedia CAN.
The multimedia interface unit (Display or Multimedia connection unit) transmits the activation signal to the radio and
to the other computers that participate in the multimedia function when the user activates the radio button.
The display shows various multimedia information such as the radio information, the time, etc.
The radio control satellite allows various functions of the radio to be accessed.
