Fault finding - Role of components
Role of main components
–Display: displays various multimedia system data such as the station selected, time, CD listing and satellite
guidance information.
–Steering column control: allows the various system functions to be used via the steering wheel control.
–Speakers and tweeters: 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 from various transmitters.
–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.
–Cartographic map DVD: loads maps into the navigation computer.
–AM/FM aerial amplifier: improves the reception of AM/FM signals.
–Multimedia network interface unit: enables information to be exchanged between the “vehicle” and “multimedia”
multiplex networks. This computer is involved in activating the multimedia system.

Fault finding - Function
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 steering column switch (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.
Possibility of re-routing according to traffic information.
–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.

Fault finding - Replacement of components
For information on removing/refitting the multimedia network interface unit, refer to the MR for the vehicle concerned:
–Scénic II ph2 (see MR 370 Mechanical systems, 83C On-board telematics system, Multimedia network
interface computer: Removal - Refitting)
–Espace IV ph2 (see MR 405 Mechanical systems, 83C On-board telematics system, Multimedia network
interface computer: Removal - Refitting)
–Trafic II ph2 (see MR 408 Mechanical systems, 83C On-board telematics system, Multimedia network
interface computer: Removal - Refitting)
–Kangoo 2 (see MR 417 Mechanical systems, 83C On-board telematics system, Multimedia network
interface computer: 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).
*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).
