I also found the same subject here that was started a year before yet there was still no solution... http://avic411.com/index.php?/topic/12889-has-anyone-used-existing-microphones-for-bt-module/page__p__186413__hl__onstar__fromsearch__1#entry186413

I had the same question... it would be convenient to be able to use the factory installed onstar microphone for my f700bt instead of finding a place to install the pioneer mic and run the cable. I no longer use onstar at all, so no need to split the mic to do 2 duties. Has anyone done this? Does anyone think this is at all possible?
