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 receives various signals from the vehicle CAN (speed, status of exterior
lights) and retransmits them for the radio via the Multimedia CAN.
The multimedia network interface 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.
–Display: displays various multimedia system data such as the station selected, time, CD listing and satellite
guidance information.
–Steering column switch: provides access to various functions of the multimedia system.
–Speakers: relay the sound from the multimedia system into the vehicle.
–CD changer: enables compact discs to be loaded and music to be relayed to the receiver.
–AM/FM aerial: receives radio signals.
–GPS aerial: receives various data transmitted by satellites.
–Radio/navigation computer: manages the various multimedia system functions according to user requests and
transmits audio data to the vehicle via the speakers.
–AM/FM aerial amplifier: improves the reception of AM and FM signals.

General operation
The multimedia system is involved in the following functions:
–Radio reception (AM, FM).
–Playing CDs/MP3 CDs/navigation map.
–Guidance and navigation system with colour screen.
–Bluetooth hands-free phone.
The use of this multimedia system allows the customer:
–To select radio stations by using the preselections, the list or manual selection.
–To have an automatically-updated radio list.
–To listen to CDs or MP3 CDs.
–To control the radio using the radio control satellite.
–To change various acoustic parameters (bass, treble, fader, etc.).
–To navigate on a colour screen (visual and audio guidance): for this function the system uses GPS, the vehicle
speed wire information and an internal gyroscope.
–To receive traffic information via RDS-TMC and to display it on the navigation map.
–To display the time and temperature on the screen.
–To use the hands-free phone function (sound relayed to the radio speakers) with a Bluetooth phone (HFP profile).
–To be protected by an immobiliser code.

SETTINGS
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 navigation computer.
–Select the menu repair mode.
–Select the other parameters menu.
–Select line VP001.
–Enter the VIN.
–Exit fault finding mode.
–Switch off the ignition.
–Wait for the end of the Powerlatch* phase (20 minutes maximum).
–Reread the VIN in the Identification menu for confirmation (ID008 VIN code).
CONFIGURATIONS
CF007: Vehicle configuration
This command is used to configure the computer according to the vehicle type.
LC001 Vehicle type can be used to confirm that the configuration has been properly entered.
Important: After switching on the system, there can be a delay of 20 seconds before dialogue is established.
*Powerlatch: Time required for injection computer supply after + 12 V after ignition feed cut-off.

For information on removing/refitting the multimedia network interface unit, refer to the MR for the vehicle concerned:
–Scénic II Phase 2 (see MR 370, Mechanical, 83C, On-board telematics system, Multimedia network interface
unit: Removal - Refitting)
–Espace IV Phase 2 (see MR 405, Mechanical, 83C, On-board telematics system, Multimedia network
interface unit: Removal - Refitting)
Operations to be carried out before replacing the multimedia network interface unit:
1. Before replacing the multimedia network interface unit (with Techline approval), perform a fault read and a
conformity check to confirm that it is defective.
2. After obtaining Techline approval, remove the multimedia network interface unit, with the ignition off (wait
1 minute for the system to shut down completely).
The multimedia network interface units available from the Parts Department are supplied unconfigured.
Operations to be carried out after replacing the multimedia network interface unit:
–Configure the multimedia network interface unit (see Configurations and Programming).
Important: After switching on the system, there can be a delay of 20 seconds before dialogue is established.
*LPN: Low Price NavigationNote:
If the LPN* radionavigation and the multimedia network interface unit (connection unit) are replaced
simultaneously, the multimedia network interface unit must be configured first (see Configurations and
programming).
