Discover Pro updating

[kalidor]

I have Passat R line 2016 and I want to update the SD navigation card. When I go into VW site it gives me the option of a
Discover Media or Discover Pro update. How do I know which system I have.

Discover Pro has the larger screen.

Media has 6,5" screen and pro has 8" screen. Media has also a small shiny dark plactic around the screen.
