I have the radio security code now I need to know how to enter it. Can you help me please? I have a 2002 Honda Civic
You can enter it using the preset buttons. You should see buttons that have numeric characters 1 through 6 or 1 through 7. Just use those to enter the code :)
You press the buttons 1 and 6 at the same time while trying to turn on the radio again.
