Hi, I am new to this forum and surprised you have not received any replies to your post, I have fitted headrest screens with inbuilt dvd players, infra red wireless headphones, and av output, plus remote controls, these are in grey leather look and match the car interior, These were purchased off ebay link included.

They were linked to the nav screen using the unit from gnet Canada, link provided.
