The mobile connectivity computer provides the link between the radio and the mobile peripherals connected to the
mobile connectivity terminal.
It transmits:
–Audio signals to the speakers via the radio.
–Display information (song title, list, etc.) to the display via the radio.
The mobile connectivity terminal enables different types of mobile medium to be connected using the USB port and
the Jack socket.
The multimedia connection unit (Display or Multimedia connection unit) receives various signals from the vehicle
CAN (speed, status of exterior lights) and retransmits them to the radio via the Multimedia CAN.
The multimedia connection unit (Display or Multimedia connection unit) transmits the activation signal to the radio
and to the other computers participating in the multimedia function when the user switches on the radio.
The display shows different multimedia information such as radio information, the time and the temperature.
The radio control satellite on the steering wheel enables the different radio functions to be accessed.

The mobile connectivity computer enables music files to be played (MP3, WMA, etc.) on:
•USB mobile peripherals (USB key, MP3 player, etc.) (Except hard disk with own power supply),
•audio peripherals via the jack socket.
The multimedia 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.
•Has anti-theft protection
Computer activation system
The mobile connectivity computer has an activation system.
The mobile connectivity computer is activated under the following conditions:
•by pressing the radio ON/OFF button,
•by starting the engine.
The mobile connectivity computer is switched off under the following conditions:
•The ignition is switched off.
•Door opened (Clio III)
•Door opened for 1 minute (New Twingo)
•By pressing the radio ON/OFF button (Clio III and New Twingo).
The multimedia connection unit (Display or Multimedia connection unit ) is activated by the UCH (central door
unlocking); this then activates the multimedia computers (Navigation, Radio, mobile connectivity computer, etc.) via
the "Activation signal" connections.
