Greetings. So, I have two twin Volvo, two S40 2004. I had to disconnect the battery on one and mistakenly entered the radio code of the other car. Did that three times because I thought I had the right code. It have me the OFF. So I went in to the hidden menu to reset that 3oo to 1oo, so it would give me the opportunity to reenter the correct code. I opened the radio and saw the right code also asked the dealer, they have me the same code. So I entered the correct code this time but it gave me an error as well. I might have mixed something up in the radio internal configuration maybe. Basically I just need to 'reset the radio back to factory settings'. Any ideas?
Thank you
