If you go into the service screen, by doing the following:
1) Hit the Menu button
2) Hit the volume buttom
3) touch top left, bottom, top left, bottom left in that order,
and you should see several buttons and one of them is phone. I haven't driven it in over a week so I'll check again tonight to make sure I didn't leave out any steps but my wife and I found it odd it was there so we assumed it's just because the actual bluetooth/phone capabilities are NOT there. The screen is with the number pad though.
