Actually, there's an easy way to check. Hold down your trunk unlock button for 3 seconds and that should set off the panic alarm if it's installed. If you have iDrive, you should be able to turn on/off the "beep" from there. If not, I don't think it can be done through the BC stalk so we can help you code it in.
