With the premium audio option, you get a JVC KD-NX5000 single-DIN navigation and stereo unit, which also includes Bluetooth cell phone integration. Also, there is a small touch screen down by the driver's left knee. Touch the wrench icon and you can choose different running modes, such as Performance and Range. Each mode will alter the car's range, acceleration, and speed to achieve specific performance goals. When the car is moving, this screen can show a power usage gauge.
