Look at your oem radio. It has a plastic insulator on the side, for the radio alarm contact. Your aftermarket radio does not have this insulator. That is why you hear a beep when you set the alarm.
2 choices. You put tape on your aftermarket radio in the area of the insulator on the oem radio. Or, you disconnect the wire to the alarm contact for the radio.
Or, leave it alone. Some people like to hear a beep when the alarm is set. The alarm still works, just not the alarm for the radio.
