I am going to connect an external dvd to the sat nav screen of my RX300.
On the back of the screen I have four connectors, one of those is for the rgb input (five wires).
I have the video to rgb conversor, the vais input device for the ipod and an extra audio input...
The project is almost finished!
But I still need the pinout meaning for each of these connectors, I donīt want to burn the screen with a miss connection...
If anybody knows the pinout meaning of this connector, I will appreciatte too much,
Thanks!
