DVD Video /BMW Aux Input Question HELP HELP X5 2006 4.8is

[LABALAI]

Hi colleagues:

I am again here asking the same thing, but before making any invesment I want to be sure of all the items that I need to buy.

This is what I need (in my new 2006 X5 4.8is):
a) I want to install the original BMW HeadRest monitor + DVD.
b) I want that the front monitor can have video on motion.
c) I want that the image of the rear monitor can be seen also in the front monitor.
d) I want that the audio of the DVD player can be heard in the Hi Fi DSP System factory installed.

I know that there is a guy (jmh) that already installed something like that but till now I do not understand what are all the items that I need to get what I want.

Till now I know that:

To satisfy point a) I will buy the Original BMW monitor and DVD system direct from the dealer in walknappa.
To satisfy point b) I will buy the TVonNav module that cost 199$.
To satisfy point c) I do not know what I need.... PLEASE HELP
To satisfy point d) I do not know what I need.... PLEASE HELP

I know that there is something call BMW Aux Input but I dont know If I need to buy this direct to the dealer, if so, what is the part number that exactly works on my 2006 X5 4.8is ????

Remember that I live in latin america and the dealer told me that they will help me to install this but I need to buy the correct parts (connector, cables, module, aux input, nuts, etc, etc)

So, you, my friends, are the only guys that can help me. I will travel to Florida and the end of October to buy all what I need so, If you can help me I can order by internet all the items and shipped it in a friend of mine address in Florida to pick up later.

Thank you very very much for this HELP.
