Hope you have your 4 digit radio code. Should be on a small card with your car manual. Have your key set to 1 or 2 position, turn the radio on It will display CODE. Enter the 4 digits. If you enter the wrong code 3 times it will display OFF. You will need to wait 2 hrs with the radio left on (ie 2 hrs non- continuous, meaning it could be 15 min here, 30 min there until you've reached a total of 2 hrs). The it will change back to CODE and you can try again. If you've lost the code, I believe you have to call Volvo with your VIN and they will provide the code to you.
