KDL unfortunately not a straight fit , I own a 2012 and the unit is 10-15mm to deep and depending on which factory facia you have , there are two the standard with is a little wider opening and a DD one made for like an Sony , Pioneer unit. Both are the incorrect size (about 3mm to narrow in the opening) as the unit is made to the correct DD sizing.
But I knew this before I brought the unit and I have both facia and I got the unit only on Friday (had a hang over on Saturday) so I aint got around to making a decision yet if to trim out the 3mm and square the corner on the new DD facia or laser cut and adaptor ring to fill the standard facia in. On the depth side of things I have the unit so now I can work around that problem of what to do. There is the main bar the dash is mounted to so it not like just cut this and all is good im sorry to say. E3io in this thread http://www.mp3car.com/newbie/156262-...or-to-not.html if you have a read Novak points out that that company use's the front screen and a Small Edition (BYBYTE BlackBox) to get the depth down, but depending on the hard wear your going to use this maybe not an option.
For me I got the case and screen and will modify / rebuild from there it was only $20 differences between getting it with or with out, plus its a nice reference point to start from, anyway I hope that helps in some way....
Wow, so the model for sale on ebay will not fit in the WRX without some modes? If thats the case i may just go with my first idea and try to fit a tablet in the dash, if i have to cut into it anyway
