I just got my 08' with nav, but no bluetooth. I know that the 09' will have nav with bluetooth. Anyone know if it possibale to update an 08' nav?

No, it is not possible. The 2009 BT solution requires both software and hardware changes to the Onstar system, the steering wheel harness to the controls as well as the interface for the bluetooth receiver. Too many changes required to make a retrofit possible. At least affordably anyway.
