DVD Image on the Front Monitor !!!! HELP

[LABALAI]

Hi again colleagues:

Please, I need a detailed instructions (steps, photos, etc) on how to make a DVD installation that allows that the same image that appears on the headrest monitors ALSO appears in the front monitor.
The point is that my BMW dealer here in Venezuela told me that this is not possible, and I told them that in the web page there are hundred of cases where the people get the image in the front monitor. Also I want that the DVD audio can be outputted by the Hi Fi. DSP System

So, they told me that BMW, by security reasons does not allow this, but they can make the installation if I refer to them the right steps to do this (funny right??).

Also, I want to know if the image in the front panel is displayed all the time during the X5 is moving, or it is also displayed when the X5 is stopped.

My X5 is August Production and it will arrive this month to my country. My X5 has the TV Option but NO NAV System because in Latin America BMW do not deliver NavSystem because there isnt. But I have all the other options, Bluetooth, TV, etc. etc.

I want to install the original BMW monitors and DVD from the dealer but they required som help on how to get the image on the front panel. also I want to know how to get the sound in the Stereo System.

Thanks by any help on wiring, photos, instructions, manuals. etc etc.
