OnStar Hardware usable for bluetooth?

[winemaker]

Howdy all. My truck is OnStar equipped, but I don't subscribe to it. Is the mic and speaker somehow usable for Blackberry with bluetooth? I'm dreaming, aren't I?
Thanks

Look in the options list on your truck mine (2009) has both on star and it has blue tooth -- the blue tooth is and option.
