Phone connection

[Patriks7]

Hey guys,

Recently joined the X5 family with a lovely 4.8is, so take it a bit easy as I'm new here.

One of the first things I noticed when I sat in the car is that the steering wheel and radio unit have buttons for use with a phone. So, obviously, I started looking into how I could connect my phone. I found the settings and tried to connect my phone, but for some reason my phone didn't see the car (it's an iPhone 5).

After a quick search, I found that my car has the following
S644A Preparation f mobile phone w Bluetooth

Is this the correct thing for what I'm trying to do? Do I need anything else for it? Or is there a possibility that something might be broken?
