I have just brought a Focus RS 2010

with a lux-pack 2, DVD SatNav, but
I cannot get the Bluetooth to work.
It has been into the Ford main dealers six times, they can get it to work as far as recieving calls and everything necessary coming up on the screen but unfortuantly there is no sound coming through the cars speakers

.
They have tried swapping the pieces with another fully functioning RS, my unit works perfectly in the other car, but the unit that has been placed in my car, again does not work, showing Bluetooth.

Cloning has also been tried between the two cars, and they now believe it is down to Canbus working problem?
Is anyone aware of anywhere in the management system where the Bluetooth could be turned off or on?
The dealer has offered to fit a parrot, but I believe this detracts from the future value of the car, and this causes some deal of annoyance as I wish to keep the car for many years with no adjustments made.
Is it something that people who remap ECUs, would know of a solution in this area? It's so far off, as if something has been turned off and needs to be turned back on.
It isn't a cost thing either, the car is under Warrenty, but they just seem to have gotten to a point where they are saying that it can't be done.
Has anyone else had this problem?
Any help would be greatly appreciated
