Is there a way that the iphone may be used through bluetooth

Is there a way that the iphone may be used through bluetooth in a three series BMW bought in January 2007?

BMW treats the iPhone as two separate devices. A cellphone and an iPod.

Any cellphone with Bluetooth as well as the iPhone will work through the bluetooth system. it's done wirelessly.

The iPod part of the iPhone will work through the iPod wired interface jack, just like a regular iPod.

It but won't show videos clips/movies you stored in the iPhone.

From BMWUSA website:

The iPhone functions with BMW vehicles equipped with BMW help with Bluetooth® handsfree calling as of the date of testing and meets or exceeds minimum standards established by BMW of North America "BMW", and this isn't a warranty for phone performance or functionality. BMW makes no guarantees or warranties as to the performance of any phone while connected to your BMW via Bluetooth® Wireless Technology. also, software releases by BMW, the phone supplier or the wireless carrier dated after testing may alter compatibility results.

Access to the iPod or the iPod application of the iPhone via the car controls and central info or radio display is only possible on cars equipped with iPod/USB interface. The iPod/USB interface is available on three and five Series with 03/07 production, the X5 with 04/07 production and the six Series with 09/07 production date. more details will be available shortly. meanwhile contact BMW of North America’s buyer Relations Department at one 831 1117 for more details.

So the answer is yes, only if you have the bluetooth module installed for calling functions and the ipod interface installed for music functions.
