Some units won't allow the beep to be disabled. Like ForPointSex said, it's to remind you to remove the faceplate. It should stop after a few seconds. Try calling sony's tech support, they'll tell ya if it can be disabled or not. If it's that big of an issue, remove the faceplate before you turn the ignition off.
