Can you help in getting bluetooth cellular phone service activated in a 2009 venza?

All I want is some help in getting the bluetooth phone service in the new 2009 venza up and running. Why all of this thing about a user name and passWord. It has been so frustrating trying to find some answers to this question. We just bought the car 2 days ago after looking at Hyundai genisis, Mercedes c. Volkswagon before we saw the venza. We ttraded in our second Hyundai Eserra and are very happy with the car. However, I would just like some help in getting the bluetooth phone survive up and running.
