RSE, Wiring Columbus Multimedia

Hi

I hope someone can help me to get RES (Rear Seat Entertainment).

I have a new Skoda Octavia with Columbus Navi and Canton Sound System. I want to mount some screens in rear seats for the kids. Is it someone that knows how to get AV/RGB or HDMI out?

As I understand the Columbus has RGB signal out, but I can’t find any screens for car with RGB input, I probably need some converter. Someone that got the wiring diagram for the Columbus?

If I use the DVD player in the car I only get sound when driving (screen stops working), is it the same with the RGB out?

The car has Wifi hot spot, is it possible to use this and stream video on two iPads in the rear seat as an alternative? Apps or sw for use?
