I have a 2012 WRX, and would like to replace the stock head unit with a multimedia system. The thing that is the most important to me is Apps, and iPhone 4s compatibility. I would love to be able to see Facebook comments on the screen, as well as scrolling text messages. Not sure if there are any units that will do this. I want to be able to view Netflix and YouTube videos on the unit as well. Need GPS navigation with lane assist.
I am looking at the Alpine INE-w927HD. Had a consult with an installer today, and he seems to think I will get all the app control with an update from Alpine.

Does anyone have this unit? Have you done anything cool with it? Would love to get input from real people.
