Just changed the battery for the first time in 2004 crv LX model. Everything fine, but radio/cd etc just has the word COde across the display and nothing will work...??? what is the code and/or how do I find it? thanks for help.

Whenever you disconnect a car battery, the radio needs to have the Security code installed. It is for theft protection. It is the code you programed into it when you bought the car. If you bought the car new, the code is usually a series of zero's, usually 3 or 4. If you bought the car used, you may have to contact the previous owner, & ask what they used as a radio code, or if they recoded it. If that is not possible, you'll have to take it to a dealer, to have the radio reprogrammed. If you have an owners manual, it will be described in there also, on how to do it all.

Look on your owners manual, if you dont have it, then go to a dealer to retrieve your code.
