You just need the serial number in order to obtain the unlock code for your radio. Just press and hold the 1&6 buttons at the same time, while turning your radio on. The serial number should then display. And then type it into the form at http://radiocodevault.com/honda/ You’ll receive the unlock code in your email. Pretty simple stuff, and avoids a dealership trip. Don’t make things more complex then they need to be. Oh and sometimes it will say ERR, or ERR5, ERR7. You’ll just need to disconnect the car battery for 30-45 minutes and then try the serial number trick again, and it should then show the serial number. Then go to the radiocodevault site and enter it.
