2001 740i cell phone

I have a 2001 740i that i just purchased and the owners manual and cell phone were missing. Did anyone find a phone that will be able to work with the hands free phone in the car and if so can you get a cradle to charge and store it?
also this car appears to have options like the steptronics manual shift and automatic shift, cold weather package but 16 in wheels so i do not know if it is a sport model?
The car just started making some noise in the engine like either the cam shaft, lifters or valve train. sounds like a diesel at idle, any information would help!!!!
Thanks
