Here's a link to the Honda website that will give you several radio codes. You need the VIN of the car that the radio came from as well as the serial number of the radio. When you punch in that info, you will get a dozen or so codes to try. Mine worked on the 8th code.

Good luck!
UPDATE: I should have noted that you should only enter the last 8 numbers of the VIN. If you try to enter the entire VIN, it will not work.
