You will first need to get your radio 'security' code: it is usually provided with the original car user manual and documentation.

Car comes with different radio model, so you will need to consult the specific radio model user manual to enter the security unlock code.

Hope it helps.

the code is in your owners hand manual. if you have lost it. any volvo dealer will get you the code if you can prove you are the owner. and provide the VIN #

If you have the security code it's easy. The code is something that either you or a previous owner entered. If you don't have the security code a trip to the dealer will be in your future.

someone (hopefully you) set the 3 or 4 digit security code on the radio. when power is disconnected, like if someone steals your radio, the radio locks and cannot be used. the code can be from 000 to 1999. the hour and minute buttons are used to enter the numbers. 2000 choices - good luck

1 turn on ignition - LOC will appear

3 press MN again until you see the last 2 digits of the code you want to try
