Comfort and Convenience
The listed on-board computer has no sensors of its own; it reads values the vehicle already measures and presents selected ones through a display the driver cycles, so the button chooses the view rather than the calculation.
Safety and Driver Assistance
Hill start assist, where listed, only holds the brakes briefly during the pedal change on an incline. It acts on a stationary car, so it contributes nothing to the gap needed while moving.
Multimedia and Connectivity
A 12V outlet carries unregulated direct current from the vehicle's electrical system, not audio or data. Anything drawing from it needs its own adapter to convert that supply into a usable charging voltage.
