When I disconnected my Battery Yesterday and then Reconnected it I guess I triggerd a security feature in the radio and now i need a code to get it to work again !
Does anybody know where i can find this code on the car or what i can do to get it to work again ?

 

That'll happen every time you disconnect the battery. You should be able to go to your local Volvo dealer and get the code for free. You might need proof of ownership and the VIN# to do so.
