The only thing you have to do is make sure Bluetooth is enabled and sync it to the car once. Then every time you get in the car with your phone a notice comes up on the screen "Bluetooth connection successful" This is how you see it if you have the navigation package and the flip up screen. I do not know how it works on the non-Navigation cars. You can dial using the voice commands by the right side steering wheel controls. The Navigation equipped system has a nice interface for all your phone contacts that it syncs the first time you connect the phone. One thing I learned is if the car is in motion you cannot scroll through your contact list on the screen. However if you set up speed dial contacts you can use the joystick to click on a speed dial contact and the car will dial it.
I know the Navigation system added about $2500 to the price but it provides a lot of features above the maps and directions. The phone interface is pretty slick. If the radio or CD is playing the radio silences and your call comes through with the hands free speaker. Then when you end the call the music returns. No fumbling to turn down the volume or pressing any buttons on the iPhone. I highly recommend the Navigation upgrade if you can swing it. You can get a nice Garmin or Tom Tom system that have some extra features over the built in system but the "cool" factor is lost if you go this route. Just not having to reach for the phone when it rings is a gigantic plus for me. I'm never going back to the old ways.
