Did you buy the car new? If so, you then received a card (about the size of a business card) with the code on it. It's usually stuffed in the inside front cover of the owner's manual folder thing. If you don't have that, the only way to get the code is to make a trip up to any Honda dealership. They usually don't charge you anything to look it up for you (which they can do by the VIN number of the vehicle if it's the same radio that came with the car originally, or with the serial number on the actually unit), but they usually require proof of ownership of the vehicle, i.e. insurance card with your name on it and I.D. If this isn't at all an option for you, I can get the code for you, it'll just require me calling a friend who isn't always easy to get ahold of.
