I just bought a used '02 Accord LX. The owner's manual talks about the code needed in some models to restart the radio once power is disconnected from it but I do not know if the radio in my car has this requirement. Does anyone know if the '02 LX (4 cylinder) came equipped with this radio? How can I tell, and if I DO need the code, will Honda be able to furnish it for me, or will I have to buy a new radio once I replace my battery?
