Mine works fine, though it does get a bit confused when voice-dialing names..... need to change the way I say some of the names (mainly the tone of my voice).
However, noticed that they changed the voice commands from the first batch of Leons (circa 55 plate - Leon TDi Sport) and the newer models (circa 07 plate - TDi FR).
For my old Sport I could press the button and used just the 'dial' command..... now I have to say 'dial name'.......
Strange...... maybe they updated the firmware?!?
Also in my old Sport, the bluetooth was prone to hanging (ie not switching back to radio at end of call)... doesn't seem to happen in the new FR!
