Comfort and Convenience
The on-board computer gathers data from the fuel and speed sensors and presents it in the instrument display, where a stalk or steering wheel button steps through consumption, range and trip readouts.
Safety and Driver Assistance
Electronic stability program addresses cornering: wheel-speed and yaw sensors detect the car turning more or less than the steering input asks, and brake pressure is applied to one wheel to pull the line back.
Multimedia and Connectivity
With audio preparation, the installed unit draws on those factory speaker runs and the aerial feed; the user selects a source and level at the unit, and sound reaches the door and dash speakers.
