Role of main components
The radio computer manages the various multimedia system functions according to user requests and transmits
audio data to the vehicle via the speakers.
The radio uses an amplified aerial system to improve radio reception.
The aerial amplifier is incorporated into the roof aerial.
The speakers reproduce the radio system's sound inside the vehicle.
The microphone allows the telephone to be used in hands-free mode via a Bluetooth connection.
The tweeters reproduce the high-frequency sounds of the radio system.
The multimedia interface 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 interface unit (Display or Multimedia connection unit) transmits the activation signal to the radio and
to the other computers that participate in the multimedia function when the user activates the radio button.
The display shows various multimedia information such as the radio information, the time, etc.
The radio control satellite allows various functions of the radio to be accessed.

The radio includes the following functions:
•Radio reception (AM, FM).
•CD/MP3 playing.
The system offers the following possibilities:
•Choose FM radio stations using the presets, the list or manual selection.
•Have access to an automatically updated FM radio list.
•Listen to CDs and MP3s.
•Control the radio using the radio control satellite.
•Have access to optimised audio and acoustic telephone configurations for each vehicle.
•Modify various acoustic parameters (base, treble, front/rear balance, etc.).
•Benefit from a connection for a CD changer.
•Possibility of connecting a peripheral with a USB port, Jack socket, etc.
•Anti-theft protection.
Computer activation system
The radio has an activation system.
The radio is switched on under the following conditions:
•by pressing the radio ON/OFF button,
•when the engine is started, the radio is switched on automatically.
The radio is switched off under the following conditions:
•The ignition is switched off.
•Door opened (Clio III)
•1 minute after a door is opened (New Twingo)
•By pressing the radio ON/OFF button (Clio III and New Twingo).
•In the last case, if the vehicle engine is running, the radio will be switched off from a user point of view, but will be
considered operational from an electrical point of view. If the ignition is switched off, the radio will be off.
The computer activation system is managed by the UCH, which activates the display with a timed + battery supply.
The activated display in turn activates all of the computers involved in the multimedia function

Thermal protection
Thermal protection is integrated in order to protect the radio.
The functions are restored when the internal temperature falls below 80˚C.
Car radio code
The radio is protected by a two-part anti-theft system:
•A 4-digit code,
•Information exchanged between the instrument panel and the radio.
This code is requested in the following cases:
•New vehicle,
•New radio,
•When a radio is swapped between vehicles.
The radio is protected by a four digit code. This code must be entered using the radio control satellite or the
radio keypad.
Entering the code using the radio control satellite:
Press the lower button on the control to confirm an entry.
Entering the code using the radio:
Enter the digits using buttons 1, 2, 3 and 4, and then confirm with button 6.
If the code is entered incorrectly, the radio will be locked (1 minute for the first error, 2 minutes for the second error,
4 minutes for the third error, etc., for a maximum of 32 minutes after each attempt).
After several attempts, if the fault is still present, contact the Techline.
Some configurations must be programmed after the code has been entered for the first time (see Configuration -
Parameters). These settings are stored when the battery is disconnected.
Reminder:
The radio will operate for approximately 2 minutes in scrambled mode without the code having been entered
(with regular warning beeps).
Note:
If the battery is disconnected, it is not necessary to re-enter the radio anti-theft code.

The pre-code is recovered by consulting ID007 Radio programming key using the diagnostic tool or by removing
the radio and noting the four characters on the barcode following the letter T (see photo below).
There are three ways to recover the radio code (4 digits):
1. Only the VIN is available: connect to code management on Renault.Net and enter the VIN. The code server
gives the original radio code entered in the World Vehicle Database (BVM).
If the code has not been entered in the BVM or is incorrect when the code is entered in the radio, follow the
procedure below:
2. The pre-code is available: go back to code management on Renault.Net, enter the pre-code and obtain the
radio code.
If this code is correct, the radio will operate again; if not, follow the procedure below:
3. On Renault.Net, write a help message to be sent to the assistance unit.
WHEN REPLACING PARTS, OR FOR AN UNKNOWN VIN, WRITE A HELP MESSAGE IN CODE
MANAGEMENT ON RENAULT.NET TO UPDATE THE DATABASE.
