According to this forum, you won't need the code for the radio in a Chevrolet. The GM radios don't lose their code when the battery is replaced.

am un renault espace ,anul 1997 , motor 2000, benzina si nu stiu ce are radioul de nu mai merge , eu acum cateva zile am schimbat bateria cu motorul oprit si cred ca acum ami trebuie codul si eu nu am manualul radio . poate cineva sa ma ajute ???????????????????? multumesc

Es Mitsubishi radio verdad?? Si lo compraste nuevo el carro, en el dealer te podrian decir el codigo... Si no vas a tener que quitar el radio apuntar los numeros de serial y modelo y hablar o ir al dealer para que te den el codigo.........

bueno si se le desconecto la bateria y por descuido no se recuerda el codigo va a ser rekerido uno en el dealer pues el radio al reparar lo de la bateria si ese fue su caso y reconectarlo otra vez va a pensar k se lo robaron y entra anti tefht y para eso rekiere el codigo sorry
