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 tuner-amplifier.
●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.

Fault finding - Replacement of components
For removing/refitting the 4R radio navigation computer, refer to the MR for the vehicle concerned:
Mégane II ph2
(see MR 364 mechanical, 83C On-board telematics system, Computer: Removal - Refitting)
Laguna II ph2
(see MR 395 mechanical, 83C On-board telematics system, Computer: Removal - Refitting)
Scénic II ph2
(see MR 370 mechanical, 83C On-board telematics system, Computer: Removal - Refitting)
Trafic II ph1 and ph2
(see MR 408 mechanical, 83C On-board telematics system, Radionavigation: Removal - Refitting)
Master ph2 and ph3
(see MR 377 mechanical, 83C On-board telematics system, Radionavigation: Removal - Refitting)
Master propulsion ph2
(see Technical Note 3818A, 83C, On-board telematics system, Radionavigation: Removal - Refitting)
Operations to be carried out before replacing the 4R radio navigation computer:
1. Before replacing the 4R radio navigation computer (with Techline approval), perform a fault read and a conformity
check to confirm that it is faulty.
2. Before removing, eject the CD.
3. Following Techline approval, remove the computer, with the ignition off (wait 1 minute for the system to shut
down completely).
The 4R radio navigation computers available from the Parts Department are supplied unconfigured and with a black
screen.
Operations to be carried out before replacing the 4R radio navigation computer:
1. Configure the computer (see Configuration and programming).
The 4R Radio Navigation computer is in factory mode following configuration (87.5 MHz FM in scrambled mode for
2 minutes).
2. Enter the 4R Radio Navigation system unlocking code
Obtaining the 4R Radio Navigation system unlocking code:
–switch on + after ignition feed (see introduction),
–if the 4R Radio Navigation system does not come on when the + after ignition feed is activated, press the
ON/OFF button on the front panel,
–connect the Clip diagnostic tool,
–note the programming key number ID012 Navigation programming key indicated in the identification menu,
–Consult Renault.net with the programming key number to obtain the 4R Radio Navigation system unlocking
code. In the event of a fault, contact the Techline,
–2 minutes after the 4R Radio Navigation system is switched on, the unlocking code is requested,
–enter the code using the radio control satellite under the steering wheel.
