need help to unlock my honda radio code. I retrieved the serial number but when I entered onto the form for radio retrieval, it is denying the process because I do not have a zip code. I have a postal code in Canada. what do I do? help please.
I also found a sticker inside the glove box but that's a 4 digit code including the digit 8 which isn't on the number pad only 1 - 6

Any suggestions would be appreciated. Thanks LOB1234
