Hey,
From what I've read your brother has purchased an MY15 mode which has an older head unit, you can confirm this by checking if he has a sports button. If he has that button then it's an MY16, if not it's an MY15 and no app connect etc will be available now or in the future, it cannot be upgraded.
Google "VW MY16" for a ton of articles on the sweeping updates VW made this June.
