Bluetooth Question

[beairmo]

I have a 2006 X5 and have a question about the bluetooth.

Has anyone figured out how to disconnect the bluetooth pairing when you want to get out of the car? If I am on the phone when I get to my destination, the hands free continues even after I shut the engine off, take out the key, and lock the doors! I have to tell whomever I am talking to to wait while I walk out the bluetooth range, which can be pretty far away. It is rather annoying. I had added an aftermarket bluetooth kit to my old 2000 528i and it disconnected when I turned the engine off, which was perfect.

There must be a simple way to disconnect the pairing so I can use the phone normally! If you know the secret, please advise.

Thanks in advance for any and all help!
