Look under the armrest
for the USB port. Insert iPhone 5 USB cable in. Select USB source at your OEM HU/iDrive. That's it.
No USB port? No steering wheel control of the iPhone 5. You will be limited to AUX input.
Contact forum vendor BimmerTech for USB alternatives if no USB in your car or just search the forum. This has been discussed too many times before.
