I have a 2002 with the phone cradle in the center console. I was able to buy one of the v60 Bluetooth puck off e-mail. once paired my 4s it now works with the radio. receive, call out and dial from radio face or other controls.
I have a 2003 unit, that had an apple adapter that can be programmed to be used through the cd function. I was able to play music from the device and when a call came in, the music would stop, but i was not able to use the phone through the speakers.. ie wireless.
