Hello, I have a Volvo V40 I with original radio, I disconnected the radio because I wanted to connect other radio, however, the input did not fit so I decided to put back the original radio and CODE appeared but I did not know the code so once I typed in a radio that was OFF other forums that you have to wait for at least 2 hours to mine I spent 10 hours and I add nothing that I already know the code because I called the previous owner of this car, what do I need to make the radio unlock and let me enter the code some button or something? I am waiting for answers
