If you have the manual with the car, check it for the radio code. It should be in there.You might be able to call the dealership and see if they have a code that they can give you.It's a code they programmed into the radio so that if you don't have the code the radio won't work. (like if it's stolen)I think Honda is the only one that puts that stupid thing on their stock radios automatically. The aftermarket ones usually will give you the option.
