Nav is standard. If you use CarPlay, Waze, Google Maps, and even Apple Maps work quite well and fill the 10.5" screen if you get that model. Android Auto is rolling out an upgrade to use the full screen. The only downside to using CP/AA is that if you get the SX with the HUD, you do not get turn by turn directions displayed. They are only in the 10.5" screen and via voice if you enable voice directions in the respective app.
