How do you reset radio on 2005 Honda Civic ex after battery went out n now recharged?

To reset the radio on a 2005 Honda Civic EX after the battery has been disconnected or died, turn the ignition to the "ON" position without starting the engine. If the radio displays "CODE," you will need to enter the radio code, which is usually found in the owner's manual or on a card provided with the vehicle. After entering the correct code, press the "Enter" button or the corresponding button to finalize the input, and the radio should restore functionality. If you don’t have the code, you may need to contact a Honda dealer for assistance.
