Hi!

I have installed a Kenwood head unit into my 2011 Legacy. I'm trying to get the steering wheel controls (with phone buttons) to work and are looking for an interface. All the interfaces i've found are for year 2008-2010 or 2012 and onwards. I've been in contact with a shop who says they can get one for the 2011 Legacy but it's three times as expensive.

Does anyone know where i can get an interface for the 2011 to a reasonable price or what the differences is between the 2010 and the 2011?
