I am sure this has come up before but I couldn't find it doing a number of searches.

I have a 2014 BRZ Premium, at least that's what the VIN number comes up as, and it has a stock 2013 head unit installed.

Bought the car used a couple of months ago and really didn't mess with the radio all that much till the other day. It had the basic owners manual but none for the radio/nav so I downloaded the 2014 manual from the Subaru site.

Right off the bat I noticed that my radio did not match any of those pictured on the first few pages. Also it only showed steering wheel mounted switches. On a hunch I downloaded the 2013 manual and lo and behold it did match my unit.

I guess the first question is, do I truly have a 2014 BRZ or was there a mid year 2013/2014 model produced? What other changes were made from 2013 to 2014 that might indicate it is not purely a 2014 model?

If it's only they had a bunch of head units and steering wheels left over after the last run of 2013's and stuck them into the first run of 2014's that's bad enough. However if it turns out the car is some kind of 2013/2014 hybrid that is missing other changes/improvements made in the 2014 model I'm going to be really pissed. At the very least this is deception on the part of Subaru and might even be considered fraud.

I'm mainly thinking of things like the weak valve spring issue that as I understand it, only appeared to be a problem in the 2013's. Is there any way I can even tell what year engine the car has?
