e39 BMW fitted centre armrest phone

[Scamp's Walker]

With all this talk of Bluetooth etc I wondered if there is a way of utilising the electronics of the fitted telephone system to allow me to just plug my phone in somewhere and use that instead of the armrest phone so that I can utilise the steering wheel controls whilst on the move? i have seen replacement adapters on ebay but have not purchased any as I have been unsure as to ehether they were compatible. Anyone hve any ideas/advice? It would save me running to mobile numbers!
