Hello,
i made a poste previously for a problem with tv modul.
The problem for the tv modul is solved (i think).

What you have to know :
originaly my bmw e46 320cd coupé have not the tv modul installed, but the mk4 gps system with 16:9 screen.
So, i decide to buy the tv modul on the net.

The tv works fine, well, i have not installed the antenna so I don't have the signal to get the picture on the screen but it does'nt matter, i just want to put one av input on the tv tuner to play dvd in my car...

So next step, i buy one av cable like this one : eBay.be: VIDEO-IN OUT Adapter für BMW TV-Tuner MK1-4 Systeme (objet 290363726916 Fin: 02-nov.-09 16:33:40 CET)

Plug and play it said... yes i plug it but it doens't play
When i plug one av device on the video in, there is some trouble with the screen, the picture oscillate, when i plug the gamecube for example, i just guess the logo of the gamecube. But the screen is not "readable"... i mean the screen oscillate (with snow)
I don't know where is the problem.
Another think, ok the screen is not readable, but i can't hear nothing, they said "mute" in the bottom center of the screen and i hear nothing

I'm lost, someone can help me please?


EDIT :
I discover something, when i touch the chassis of the tv tuner, the screen become more stable and i can see color but the screen continue to scroll... is there a ground problem somewhere?
