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.

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).

Remove the card from the reader or the key from the ignition, then check the condition of the battery, component
code 107.
Check the battery: leaks, incorrectly fitted, loosened battery terminal, and corrosion.
Check the earth connections of the vehicle: battery/chassis, engine/chassis, starter/engine, alternator/engine,
gearbox/chassis.
If the fault is detected, resolve the abnormal contact fault.
Check the battery and perform an alternator supply test (see 16A, Starting, Charging).
Check the condition of fuse F15 (30 A) for Espace IV Phase 2 or fuse SHUNT (2AA) for Scénic II Phase 2.
Check the connection and condition of the connectors of the multimedia network interface unit computer,
component code 1714, depending on the vehicle equipment.
If any connectors are faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connectors, otherwise replace the wiring.
Disconnect the computer connector and check the conformity of the following connections:
•BP3A between components 260 and 1714 (for Espace IV Phase 2),
•BCP3 between components 260 and 1714 (for Scénic II Phase 2),
•BPT between components 645 and 1714 (for Scénic II Phase 2),
•MAN between component 1714 and earth (for Scénic II Phase 2),
•NC between component 1714 and earth (for Espace IV Phase 2).
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
