You unlock it by inserting the 5 digit code which is specific toyour radio. If you do not have the code, you will have to contactyour Honda Dealer. The original selling dealer may have the code onfile. If not you will have to remove the radio and get the serial #off the chassis. With this serial # any Honda dealer can providethe correct code. There is no other way to unlock the radio thanwith that code.
You can also go to the Honda Owner's Link I will post and signup. On that link with your VIN # you can get the code if the radiois an OEM radio.
