Role of main components
–Multimedia network interface unit: enables information to be exchanged between the “vehicle” and “multimedia”
multiplex networks.
The multimedia network interface unit is integrated into the display computer on vehicles not equipped with a
navigation system.
If the vehicle is equipped with a navigation system, the multimedia network interface unit is a computer which is
independent of the display: the multimedia connection unit, located behind the glovebox on the passenger side.
The multimedia connection 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 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 or starts the
vehicle.
The multimedia connection unit is involved in the radio anti-theft protection system.
The protection is based on an identifier, the "Vehicle ID", sent on the CAN-V by the instrument panel computer. The
multimedia connection unit reads the "Vehicle ID" on the CAN-V and sends it to the CAN-M for the multimedia type
computers.
The multimedia connection unit allows the optimum configuration of the sound volume according to the vehicle
speed.
–Display: displays various multimedia system data such as the station selected, time, CD listing and satellite
guidance information.
–Radio control satellite: allows the different functions of the multimedia system to be accessed through the radio
control satellite.
–Radio/navigation computer: manages the various multimedia system functions according to user requests and
transmits audio data to the vehicle via the speakers.

VP001: "Write VIN"
This command permits manual entry of the vehicle's VIN into the computer. Use this command each time the
computer is replaced. The VIN number is inscribed on the manufacturer's plate.
Procedure for writing the VIN
–Establish dialogue with the computer of the multimedia connection unit
–Select the Repair mode menu.
–Select the Other parameters menu.
–Select line VP001 Write VIN.
–Enter the VIN.
–Exit fault finding mode.
–Switch off the ignition.
–Wait 5 seconds.
–Reread the VIN in the Identification menu for confirmation (ID008 VIN code).
SC002: Vehicle identifier (Only for New Twingo)
This command is used to obtain the vehicle identifier. The SC002 is used to read the "Vehicle ID" entered in the
instrument panel computer and to enter it in the multimedia connection unit and in the display. The vehicle identifier
is contained in this "Vehicle ID".
This command is to be used each time the computer is replaced. The radio will be locked if it does not read a correct
vehicle identifier.
