Like everyone said, you need the security code. Honda dealerships can give you the code. Some will charge, some wont. You will have to provide them the serial number off of the radio and your VIN. There are times when the code is written in the owner's manual or is written in the glove box. I have even heard of an instance where it was written in the trunk somewhere. :dunno:
