hey, sorry for the late reply, but hope this helps and works as a guide for anyone else with this issue.
1. First, you need make sure your stereo is off, then hold down the 1st & 6th preset buttons for the radio while turning the stereo back on.
2. A batch of 8 different numbers (your stereo's serial code) will appear for about 20 seconds, write them down.
3. Contact your local honda dealer and let them know you need the 5-digit code for the decoding process and then give them the 8-digit serial code you got from the first step. They will give you the 5-digit code which you can then enter into the stereo by again turning on the stereo and pushing the according preset buttons.
4. The stereo will give you 10 tries before it locks you out as a safety feature and then you will have to wait an hour or disconnect the battery and try again. Hopefully you can enter the code in less than 10 tries anyway. (IMG:
