Hello every one!, im from México, I have an acura tl 2004, I need the radio code, I get the serial number removing the radio, it is the same that is in the glove box, now i have a code with that serial, but it doesn't work, so i did the process of press 1 and 6, and it shows a different serial number, the first four digits are the same that are in the sticker of the radio and the glove box, but the last four are different, I tried to get a New code of the acura page, but it says that the serial dont match with the vin, but why the radio shows a different last four digits of the sticker in the radio and the glove box? What can I do? Thanks!!
