Turn the key in the ignition so that the radio will come on, leave the radio switched on for 2.5 to 3hrs.
After this time it should be requesting the security code again
Input your code; if you don't have it -call the local Volvo dealer (have your chassis / VIN identification number and the registration plate number to hand , they may need it)
Tell the dealer your stereo is requesting a code you don't have ...
Do not pay any money..they all have it on a data base ..so if they ask for money hang up and call another !
anyway, get your code input it and voila ..music again, ah sweet music, I've just beenwithout music in my Volvo for a month and just found all the above out, sawthis question and just had to answer.
If the display says "Off" the radio is locked from incorrect code input.
You need to leave the key in the accessory position with the radio on (display reads 'Off') for about two hours. After that it should ask for he code again. You have three tries before it locks again. Some radios are different, but typically you use the knob to adjust the numbers, push the knob in to move to the next number
I would try removing either the two fuses for the radio or disconnecting the ground on the battery for a while. When you start the car it should rest from "OFF" to "CDE" and you will be able to enter code again
Same problem with mine, same model etc. If you input code incorrectly 3 times the word 'OFF' appears. Then you need to leave the ignition in the first position with the radio on with the word off appearing for 2 hours. It then asks you for the code again. Ring your volvo dealer and give them your registration plate number. They should have the code on file. They should not charge for this. My problem is that volvo's code that they have stored does not work so i'm waiting for a repair guy to ring me back. Suspect my stereo was 'swapped out' during a service call. Might explain the cd skipping.
