Look what I got, please tell what I'll need. A DVD+NAV question.

[Christiano]

Recently I've got a X5 4.8 is 2006. I saw that my car has NOT a DVD player and Navigation. He never has both, I think (cause I can't see any marks of some old install in the rear left trunk).
I take some pics of what I have. Please, fell free to tell me what do I need to install the OEM BT phone and Navigation in my car.

Thank's a lot. Here's the pics (BTW the televisions works good!):




I just have a CD Changer. Look, there's no marks of older intallations or removed things.




This plug is below the CD changer, in the right side.



This blue plug is on the left of the cd changer, near the tail light plug.




Can you help me?
