Picked my car up on Saturday

Lovely to drive, I'll get the obligatory pics up soon.
Anyway the lead that came with the car was a MDI ipod lightning connector.
I don't have the new iphone but since my daughter has one and will be driving the car occasionally I thought that's fair enough.
So as the salesman is showing me various controls I noticed the port in front of the gear stick where the ashtray should logically be, the port is a normal USB port yet the salesman claims the car came with a MDI lead?
He didn't have a clue what lead I should have got so I made the long drive home leadless

Is the USB port now standard?
What lead should I have got?
