I think you are assuming that to reset the check engine light you can just disconnect the battery. Disconnecting the battery on a 2004 OBD2 compliant vehicle will not reset the check engine light. It must be reset with an OBD2 scan tool. This would work on OBD1 vehicle but not on OBD2 vehicles. So the radio issue is mute.
