Passat 2011 Headrest Media Screen Query

[gtaft1981]

Hi,

I'm viewing a 2011 Passat with original VW media screens in the headrests. I've no experience of using these in any car and was wondering how they work. From the advert photos there seems to be a USB socket. Do you simply connect your smartphone to the unit using a USB cable and whatever you're watching on your smartphone (Netflix, Amazon etc) it is shown on the screens? Are they DVD compatible as well?

Hopefully someone can help.
