Just wondering if it is possible to bluetooth my phone to the onstar in my truck? The subscription has run out a long time ago, but is there still a way to do it? Friend of mine does it and he has an 09 (mines an 08), and I was looking on his sticker and it said as an option "bluetooth for phone". I'm assuming GM just started doing this in 09. Mine doesn't have that option on the sticker. Is it possible? If not, what are some other options to bluetooth my iPhone for handsfree calling while driving?
