If your car doesn't have Nav already, then no. The plugs on the back might be different, but I know for certain that unless your car has the other required components for Nav to work, then it won't. The head unit itself is only one part of it.
If it's just like yours and your just replacing it because it tore up or something, then yes it'll work just fine. 2014-2016 is the same car, just different trim levels.
