Your 2010, falls into the same category as the 2009 to 2011's. Check your glovebox, if one of the codes is "C66", then you already have brackets etc, ready for kit #96992824. Or you can piece it together like some guys. Happy hunting.
I THINK it's still possible to add a/c without the C66 code, but you'll need to scrounge up a few extra parts. Maybe someone else can confirm this.
