Having some doubts

Hy to everyone. I have a few questions

First does anyone know how much does cost these two displays for backseats from the image and can they be connected to Bolero, do they have built in dvd reader and if they dont have it is there any way to watch dvds in my car beacuse i have Bolero and it cant read dvds. If there is way I would but it only from my authorized dealer, where is the car bought so only skoda original multimedia

Here is a pic of display,also would you buy Columbus chinese duplicate and if you can tell reasons why and why not.
