Has anybody managed to get the iPhone to stream music to a 350Z's s audio system with Bluetooth. Supposedly the new 3.0 OS has Bluetooth 2.0, which can stream stereo.

 

Both your phone and deck have to support the A2DP (Advanced Audio Distribution Profile)protocol for it to work. Just because you have BT doesn't necessarily mean you have A2DP. iPhones should have A2DP but a quick google search on "iPhones A2DP" show tutorials due to some issues.
This a great feature though. I have a JVC A805 BT'd to my Blackberry.
