I was reading that there is a bluetooth kit from bmw for vehicles built after 4/2001 if they have Option 640A, How to determine what and if I have Option 640A
Does anyone even know what option 640A is??

From previous threads on this subject, it is the pre-wiring for the cell phone, and supposedly all US 3 series have it.

3 series, not Z3 series. Actually E46 3 series.
