None what so ever.
Today, I plugged in my MP3 thinking this is going to take a while to figure out well, 10seconds later, im using the MP3 player AND CONTROLLING IT VIA THE STEERING WHEEL CONTROLS!!! I was elated.
I also like how when you switch off the car, the courtesy light comes on gradually BEFORE you open any doors. Nice touch.
There are lots of nice touches you will realise after you had your car for a week or so.
