I just purchased a 2004 honda accord ex. The car radio displays a message to enter a code number. I am not sure what that is all about. Any ideas. I am sure it has something to do with the battery the dealer just replaced. The dealer was clueless since it was used and not the type of cars they sell.
You're right. When the battery gets dis-connected the radio needs a code to be turned back on. Look in your glove box to see if it might be in your owner's manual.
There is a code written on a separate little card that the previous owner might have kept. If not, you need to remove the radio and give the serial number to a Honda dealership so that they can get the code for you. Be sure and keep this code in a safe place so this doesn't happen to you again. Good Luck.
