I have a 2005 accord, and this worked for me.

1)Turn on engine w/ radio off. Push and hold down buttons 1, 6, and power.
2)I got the letter "U" followed by 4 numbers and then letter "L" followed by 4 numbers; write down those numbers.
3) Go to Honda.com
4)Click on Owners home link.
5)On that page you should see an option for retrieving radio codes for honda/acura
6)you will need to enter Vin#, home phone number and zip code fo the original owner. This will then give you the radio code..

If an audio unit with theft protection is disconnected from electrical power, you must enter a unique code number into the unit or it will not work. This code and the audio unit’s serial number are listed on the anti-theft ID card that comes with the vehicle. If this card is lost, you must obtain the audio unit serial number in order to get the radio code. Some newer vehicles allow you to retrieve the audio unit serial number electronically from the radio (some people say that they find the code on a sticker in the glove compartment, but I wouldn't count on that). Refer to your owner’s manual for the specific procedure (the following usually will work: Turn the radio off. Push the preset 1, preset 6, and power buttons at the same time, then quickly release. The number will come up in two sets)
Once you have the audio unit serial number, you can call Auto Customer Service at (800) 999-1009 or have the dealer look up the radio code.
Hope this helps you.
