Well Another MINI, another set of questions again

!
The next MINI we are buying, has some sort of Bluetooth Device / Kit. Any help would be appreciated so i know exactly what it is
Firstly, a button on panel next to Steering Wheel, labellled 'Tm' or something similar. What does it do? Is it Bluetooth option installed by MINI? How does it work?
Secondly, theres a Sony Ericcson Bluetooth device by Steering Wheel, with a wire running to it from panel. Call buttons are on it, i assume this is a non-bmw mini modification? In all honesty ill probably remove it.
So back to First Q, whats the button

. Maybe its Knight Rider in disguise or has rocket boosters on demand

Thanks
