i have a cio 2001. and somehow ive managed to reset the radio on my car?

hi, i tried to put code in for my radio which i was given with the clio but was the wrong code . removed radio and a code was marked on the side,put this code in and worked first time. some one must have changed radio at some time.each radio has its own code so if you put this in by chance you was very lucky
