Hiya,
right.....
The Advanced Telephone Kit works by you putting you phone inside the special inductive pocket which is located in the centre armrest, you will also get a USB charge point in there too, just use your normal iPhone/Android cable. The port is only for power and doesn't link to anything else in the car.
The MDI port is located in the front cubby hole ahead of the gear knob, you should get a iPhone MDI cable with the car, some have been lucky to get both the iPhone 4 30-pin cable and the iPhone 5 lightening cable, others didn't get one and some like myself managed to get the dealership to swap my blue collar cable for the red one.
If you want album art and the ability to play iTunes movie try and get the red MDI iPhone 4 cable, the iPhone 5 has a green collar and worths just like the red one.
Hope that helps.
