I just spent the last 45 minutes looking in all the recommended spots...no codes, no S/N. Any chance you can PM me the magical two button combo?I lived this experience a few months ago. The battery was dead. Called the Auto Club. They arrive, put a "booster" plug thru one of the accessory ports and replace the battery. After the main battery was in place, the booster was removed, along with the memory settings of the radio code. So, I removed the radio from the dash and go to my nearest Honda dealership. The service advisor (after verifing my identity) calls a number and is given two possible codes and neither one work. Service advisor has me reinstall the radio in the dash, push two buttons at the same time which displayed my code. I entered the code and voila, it worked.
Nowhere in the glove box or on the radio itself was there a sticker printed with the radio code on it. Frustrating as heck, but an evil necessity to get my radio working again.
As bad as the factory radio is, no music at all is even worse. Thanks for the help.
