'bout to buy a 99 accord, stereo when turned on says "CODE E"

Whats this mean, what do I do? Thanks

 

Any time the battery is disconnected, the security code for the radio will need to be entered. Look in the owner's manual for a card with code on it. If you can't find that card or the code is not documented in the owner's manual, you will have to call your local Honda dealer and give them the radio serial number (remove the radio) and vehicle VIN. They can them give you the correct code to enter. The radio should work then. This one thing I don't quite understand, Who would want to steal a factory Honda radio?!
