every car has a different code..... you don't have to TAKE it to the dealer... just call them, they will give you the code over the phone (assuming you have all the info they ask, VIN, make, model, etc..)
I bought a used 97 328i and can't find the radio code card anywhere. I really don't want to take to the dealer. Can anyone help? I have all the info for the radio. - Thanks in advance
