Then the antenna is also controlled by the phone 'system'
The the phone system is ON the antenna will be up and ready to receive calls. It doesn't matter if your hand held unit is unplugged or not. So you need to plug the hand unit back on, then power it off and the 'system' will then know it is OFF. If you unplug it when its power is ON, the system will treat it as being on (and the antenna stays up).
BUT there is also battery saving feature : when you remove the key, you can still turn on the head unit to p[lay music or to use the phone, buy only for about an hour, then they will be turned off automatically to save your battery.
