It looks like you have enhanced connectivity, so if the dealer tries to offer you a "Y" cable, say no and ask for something more useful.
The standard apple cable works much much better.
Make sure you have a cup holder cover on the centre console. Mine didn't, or at least that's how it appeared at the time. The dealer pinched another one from a display model. A couple of weeks later I found the original under the front seat.
Enjoy!
