Good evening- i will try to help as best as i can.First question did you get any books with the car?If you did look through them and see if you can find a card(the size of a credit card) that reads radio code with a five digit number.If not you need to remove the radio and get the serial number off of it.reply to this answer with the serial number and brand of radio and i will retrieve the code.
