I have a new 2012 also. From my research the only things that have changed are what mikeb33 said, the steering wheel cruise control buttons are on the steering wheel (that likely means all the internals of the steering wheel are changed too) and you can now manual select each gear in the 6 speed auto transmission. Not a new transmission, just new logic. 2009-11 have the 6 speed but they only used 5 of those gears, skipped the 5th gear into 6th. Kinda silly.
The tow hook addition requires cutting out a portion of the front plastic fascia unless your fascia already has holes to accept them. Easy job with a dremel and small torch to melt/smooth out the roof edges and make them shine if you want. It is a well documented job on the forum, just search for tow hooks. I would get them but Im getting a bully bar or brushguard eventually so I dont want to buy them and then have to sell them when I get back to the states.
While most parts havent changed, many factory and dealer options have and how they relate to other options.
