DVD Questions X5 2005 4.8is

[LABALAI]

Hi Guys:

I just received my BMW X5 4.8is this week. I want to install the HeadRest BMW monitor and the DVD Player, I have some questions:

1) It is possible to have the same image of the headrest monitor in the front panel monitor?
2) Is the sound of the DVD player outputted by the Hi Fi Stereo System DSP, or it is only possible to hear it using the headphones ?

The point is that I want to have the option to hear, for example, a U2 Concert via the Hi Fi DSP system playing the DVD disc on the DVD Player and seeing on the front monitor also.

Otherwise I will not install any DVD option.

Thanks a lot.
