Does anyone know of a way to keep bluetooth turn OFF on my DI, but have it automatically turn on when I turn on my bluetooth headset to make a phone call? The reason I ask is because when I leave it on all day, it drains my battery. Ideally, I'd only like it to turn on when needed (i.e. when I need to make a call and turn on my BT headset). I know I can manually press the bluetooth toggle switch on the phone, but there's got to be an easier way. My BB curve could do this, so I would assume this phone could do it as well. TIA!
