ford mondeo green phone muting radio?

I've just bought an 08 mondeo with the ford 6000cd in it. I've bought it believing I could connect to the Bluetooth for hands free but pressing the green phone only mutes the radio?
I've had a look on line and I'm not sure if it needs rebooting or if there's no module fitted for the Bluetooth?
Any ideas on how to find out if its got Bluetooth available would be a massive help
thanks
