Does anyone know if its posible to stream live audio through the bluetooth telematics in the E70?

i know it can be done with many of the new bluetooth compatible car stereos with near perfect cd quality!

i just changed my mobile out for the Sony W910i and tried it out on a friends Sony bluetooth head unit in his car, sound quality was really good. would be good to know if anyone has tried this....
