BT Call Oddities

[Nanniepoo]

Have an '08 X5 4.8. When making a phone call over Bluetooth, how do you disconnect the phone and leave the vehicle?

By either turning off the car, or disconnecting the phone and then turning the car off, the radio stays on. No idea how to turn it off. And that's both the fob that has CA, and mine, which I need to insert. Radio still will be on after pulling the fob out. I'm kind of assuming it will eventually turn itself off, but still extremely annoying. I come home and my wife is frequently just sitting idling in her car because she can't shut it off and continue the phone call.
