Comfort and Convenience
The listed air conditioner cools and dries incoming air, while the on-board computer simply reads data from vehicle sensors and displays it. One conditions the cabin; the other only reports on consumption and trip figures.
Safety and Driver Assistance
Hill start assist matters on an incline with a manual gearbox: it briefly holds brake pressure after the pedal is released, giving time to engage the clutch without the car rolling back.
Multimedia and Connectivity
The listed AUX input carries an analogue audio signal only, so it passes sound from a connected device without transferring track names or allowing control of that device from the audio system.
