Which of these systems does your vehicle have ?
Audio System The audio system is enabled when the key is in RUN or ACC. The accessory delay function allows the audio unit to be operated for a preset period of time after the key has been turned to OFF and a front door has not been opened.
The speakers are powered either directly by the audio unit (all except THX®) or by the audio amplifiers (THX®). The subwoofers are powered by their own amplifier (Audiophile) or by the audio amplifiers (THX®).
The following audio systems are available:

• Base

    1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
    1. If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
       • check that the program card is correctly installed.
       • check the connections to the vehicle.
       • check the ignition switch position.
    1. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
    1. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
       • CAN circuit fault; all electronic control units no response/not equipped, refer to Section 418-00 .
       • No response/not equipped for the audio unit, Go To Pinpoint Test A .
       • NOTE: Do not press any buttons on the audio unit while the audio unit is carrying out the self-test.
         System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out self-test diagnostics for the audio unit.
    1. If the DTCs retrieved are related to the concern, go to Audio Unit Diagnostic Trouble Code (DTC) Index.
    1. If no DTCs related to the concern are retrieved, and the concern is not visually evident, proceed to the Speaker Walk-Around Test and the Audio Unit Self-Diagnostic Mode.

before you press the cd on button keep holding the eject button while you press power on, I know this works for computers etc.

disconnect the battery for 30 min. then reconnect . the radio will ask for the code again . type it in & you should be good to go . Good Luck

Could be mute controls for the telephone. The voice for the Navigation is adjusted separately from the radio volume. If any work was done on the vehicle, like a battery disconnect, then radio controls may need to be reset.

You need to toggle through the Menu to things like screen brightness for the Navigation.

You also have a speed sensitive radio and the volume controls could be affected by these settings.

Look on the glove box door for a little white sticker with the code numbers on it.Use the numbered buttons to enter. Some code numbers are written down in front of the owners manual too. reply

It's no way to change the version, you have to replace command with the English version command unit, and also have to buy the navigation DVD from dealer, is this information helped you?

either u have the wrong code or u r waiting to long to enter the unloc code check with ur dealer about ur code they may have given u the wrong code when u bought the car ,could have been written down wrong,or ur radio may have a problem if u give the dealer the radio id code and ur unloc code [s]he can verify if their correct good luck

All new cars are alike and use snaps and clips to hold everything together. Most likly you can remove the trim around the in dash radio unit with a thin metal tool. They have special tools at the car dealer for this. I know with the older model hyundai's there are two clips at the bottom of the front panel where the cigarette lighter thing is. Once you do find a way to remove the front panel there most likly are screws holding the radio unit in. I myself am about to remove my radio unit but I am just gonna stop in to my dealer and see what tool to use.

The radio fuse should be written inside the panel cover.

The first step is to try and remove the radio to see if the code has been written on the casing. This is sometimes done with Volvo.

You will also need to provide the model number printed on the front of your stereo as Volvo branded units are often Clarion or another major brand that has been re-branded Volvo.
