Comfort and Convenience
Seating position is a common preference: some people sit upright and close to the wheel, others further back. Height, reach and driving habits all feed into it, which is why no single setting suits everyone.
Safety and Driver Assistance
Learning where the lights, wipers and demister controls sit before setting off means less fumbling later. A few minutes spent while parked is easier than working it out in traffic or poor weather.
Multimedia and Connectivity
Keeping a phone charged on longer trips is a practical concern in its own right, separate from calls or music. If charging is available, it decides whether navigation can run without watching the battery.
