Bluetooth integration
 

In an attempt to modernize my car a little bit, I have been thinking of installing bluetooth into my Rx-7's stock stereo system so that I can link my bluetooth-ready cell phone to the car's speakers to hear the conversations. I am not a big fan of aftermarket parts, so I am wondering if the stock Bose stereo can support bluetooth? Has anyone tried this before?

If this doesn't work, then perhaps one of the later Mazda headunits (such as the Protege's) could work?
