You can also use A2DP toggle From teksoft... its free and it has command line params to toggle the BT on or off on top of toggling the BT Stereo to your headset. ( so it says *)
I use it on mine to redirect the stereo to my FM transmitter...

* I had the command line to toggle BT and Stereo ON, and i expected it to put on BT and then the Stereo, but for some reason I have to click twice on the same shortcut ( on my M2D) for it to enable both icons in the task bar but it works ... clicking twice was not an issue since it works . Also I expected it to turn off if they are ON already ( hence the word Toggle) but this didnt work unless I create another shortcut to specify to turn OFF ... Not really a big deal since this is free, so i create an ON shortcut and an OFF shortcut to help save on the batteries when i do not need it. If ytou get it to work as a Toggle using 1 shortcut let me know!
