If your screen has got the phone 'option' on it, you have Bluetooth. It's a rubbish system to connect to, but lift up the armrest while the car is off, hold down the phone looking button (assuming you have one there) and turn the car round to ignition 1 and after 4 seconds or so take your finger off the button. If you have bluetooth, your system will tell you the car is in pairing mode. If nothing happens, you don't have it.

Heaps of options for bluetooth, the integrated system is good, but not worth $1200.

Having said all of that, a 2006 4.8 would definitely have all the specs.
