Okay, i'm still looking for just a flat out answer, even though it's pretty basic, and i've searched for it. How would i go about using my iPhone to play music over the cars speakers, and possibly make / take calls (using bluetooth). I found this, but how? http://forums.macrumors.com/showthread.php?t=322156 I don't have the car yet, but it's a 2004/2005 Infiniti G35. Thanks.
