Leave the radio on for an hour or so and it will go from "OFF" to "CODE". At that point you can enter the correct code to turn on the radio. You can get the code from the Volvo Dealership.

You can try the code again in 2 hours, if you have the wrong code, call a Volvo dealer with the serial and part # and they can give you the code
