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.

The radio includes the following functions:
•Radio reception (AM, FM).
•CD/MP3 playing.
•Hands-free for Bluetooth telephones.
•Voice recognition for telephone functions
•Audio reading of a Bluetooth peripheral (Telephone for example).
The system offers the following possibilities:
•Choose FM radio stations using the presets, the list or manual selection.
•Have access to an automatically updated FM radio list.
•Listen to CDs and MP3s.
•Control the radio using the radio control satellite.
•Have access to optimised audio and acoustic telephone configurations for each vehicle according to the vehicle
type.
•Modify various acoustic parameters (base, treble, front/rear balance, etc.).
•Use the hands-free telephone function (sound relayed towards the radio speakers) with a Bluetooth telephone.
•Use voice recognition for the telephone functions (button on the radio control satellite). The voice identifier can be
recorded.
•Benefit from a connection for a CD changer.
•Possibility of connecting a peripheral with a USB port, Jack socket, etc.
•Anti-theft protection
Computer activation system
The radio has an activation system.
The radio is switched on under the following conditions:
•by pressing the radio ON/OFF button,
•when the engine is started, the radio is switched on automatically.
The radio is switched off under the following conditions:
•The ignition is switched off.
•Door opened (Clio III)
•1 minute after a door is opened (New Twingo)
•By pressing the radio ON/OFF button (Clio III and New Twingo).
In the last case, if the vehicle engine is running, the radio will be switched off from a user point of view, but will be
considered operational from an electrical point of view. If the ignition is switched off, the radio will be off.
The multimedia interface unit (Display or Multimedia connection unit) is activated by the UCH (central door
unlocking); this then activates the multimedia computers (Navigation, Radio, etc.) via the "Activation signal"
connections.
