2006 X5 4.8is iPod Interface

[sam48is]

Hi, I'm about to buy a 2006 X5 4.8is (with NAV and TV option) and would like to know my entertainment options available with this car, especially for music. Does it come with an iPod interface built-in, or do I need to buy third-party cables and drill holes and all that mess? What would I need to do here?

Are there any AV connections in the back cargo area that can be used? how and for what?

I also have the AV in/out 3.5mm jacks on the back of the center console facing the rear seats (with a Play button)... I already read some threads about that and it doesn't seem to be too useful.

So I'm curious what this car can do out of the box or with one or two simple cables. I don't want to drill any holes or have to disassemble half the car.
