Modern vehicle user interfaces combine a central touchscreen, voice control, steering-wheel buttons and often a head-up display. As of October 2026 they mirror phones through Apple CarPlay or Android Auto, can run built-in systems such as Android Automotive, control vehicle settings, display driver-assistance alerts, and increasingly keep physical buttons for safety-critical functions.
Key Takeaways
- Phone projection is standard: Apple says more than 800 car and motorcycle models support CarPlay, and Android Auto has been available since March 2015.
- Some cars now run the interface on the car itself: the Polestar 2, delivered from July 2020, was the first car with built-in Android Automotive.
- Voice control reduces handling of the phone but not all distraction; AAA Foundation research found attention could stay impaired for up to 27 seconds after a voice task.
- From 2026, Euro NCAP requires physical controls for indicators, hazard lights, wipers, the horn and eCall/SOS for top safety ratings.
- Screens keep growing: BMW’s Panoramic Vision projects information across the lower windshield on the Neue Klasse iX3.
Over the past decade, in-vehicle connectivity has advanced rapidly, from basic radios with a Bluetooth phone connection to large touchscreens linked to the driver’s smartphone and the internet. While at one time, the interface was pretty basic, these days you have touch-screen interfaces armed with some pretty impressive features and technologies.
Some newer models sold through dealer groups such as Peter Vardy, a Scottish car dealer group that left the Vauxhall franchise network in July 2021 and now runs used-car supermarkets and other franchises, were described when this article was first written as integrating social media apps such as Facebook into the interface design. As of October 2026, phone-projection systems such as Apple CarPlay limit messaging to audio-first apps (for example WhatsApp and Telegram) rather than scrolling social feeds.
Here, we’ll look at just some of the things modern vehicle user interfaces are capable of.
Entertainment and communication
Recent developments in in-car user interfaces have transformed entertainment and communication. From voice control through to messaging and Bluetooth capabilities – you can do so much more in modern vehicles than you ever could.
As the world has become so much more connected, there’s been a need for car manufacturers to develop user interface systems which allow connectivity in a safe environment. This has led to voice-controlled messaging, which lets drivers dictate and listen to texts without picking up the phone. Hands-free is not the same as risk-free: studies for the AAA Foundation for Traffic Safety by the University of Utah found drivers could remain distracted for up to 27 seconds after a voice command.
They have also made it much easier to listen to music, letting drivers connect a smartphone (or, in older cars, an iPod, a line Apple discontinued in May 2022) by USB or Bluetooth for quick and easy music streaming.
Driving assistance technology
It’s not just entertainment and communication which has been improved on modern interface systems. Driving assistance technology is also helping to improve both efficiency and safety within the vehicle.
Take Tesla cars for example. Their interface is a large touchscreen display, allowing the driver to access practically every setting in the vehicle. Many functions, from the lights to the doors (and, on models that had one, the sunroof), are controlled from the touchscreen; the Tesla Model 3 uses a 15.4-inch center display. Tesla removed the turn-signal stalk in the 2023 Model 3 refresh and later returned it for the 2026 model year, a sign of how carmakers are rethinking touch-only controls.
The future of the in-car interface
While modern user interface systems have become a lot more advanced in recent years, we can expect them to become even more complex in the not too distant future. Screens have kept growing: the BMW iX3 pairs a 17.9-inch central display with a 43.3-inch projected strip across the base of the windshield. At the same time, safety bodies are pushing back on touch-only controls, so the number of on-screen controls is no longer simply rising.
As cars are becoming more autonomous, the interface is also going to start including different types of features. In conditionally automated (SAE Level 3) systems such as Mercedes-Benz Drive Pilot, the driver does not have to supervise the car within approved conditions, which makes room for more entertainment apps. In Level 2 systems, which describe most driver-assistance packages, the driver must still supervise at all times.
Windshield displays have moved from talk to production: BMW’s Panoramic Vision, first fitted to the Neue Klasse iX3 built from October 2025, projects driving and infotainment information across the full width of the lower windshield. A fully interactive window display controlled from the rear seats has not yet become a mainstream feature.
Overall, modern user interfaces in cars have improved dramatically over the years. Drivers now have much more control over the car’s functions, as well as a huge range of connectivity and entertainment options.
Development continues on two fronts: deeper software integration, such as CarPlay Ultra and Android Automotive, and simpler layouts that bring back physical controls for core driving functions. The goal is not just more complexity: the best interfaces add features while reducing the time drivers spend looking away from the road.
What Can a Modern Car Infotainment System Do?
A modern car infotainment system is the screen-and-software hub that handles navigation, media, phone calls, messages and many vehicle settings. The table below summarizes the main capabilities and the technology behind each one.
| Capability | How it works | Examples |
|---|---|---|
| Phone projection | The phone runs the apps and the car screen displays them | Apple CarPlay, Android Auto |
| Built-in operating system | Apps run on the car’s own hardware without a phone | Android Automotive (Polestar 2, Volvo, Renault, Ford, GM) |
| Voice control | Dictation and spoken commands for calls, messages, music and navigation | Siri in CarPlay, voice commands in Android Auto |
| Vehicle settings | Climate, lights, driving modes and other settings through the touchscreen | Tesla Model 3, CarPlay Ultra on supported cars |
| Driver-assistance display | Warnings and status of systems such as speed assistance and drowsiness warnings | Instrument cluster and head-up displays |
| Head-up and windshield displays | Information projected into the driver’s view | BMW Panoramic Vision on the iX3 |
Apple CarPlay vs Android Auto vs Android Automotive
Apple CarPlay lets a car’s head unit act as a display and controller for an iPhone. Apple announced it as “iOS in the Car” at WWDC 2013 and launched it as CarPlay at the Geneva Motor Show in March 2014, with Ferrari, Mercedes-Benz and Volvo among the first supporters. It works with iPhone 5 and later and connects by USB or, in some cars, wirelessly.
Android Auto is Google’s equivalent for Android phones. It was revealed at Google I/O 2014, released to the public on March 19, 2015, and first offered by Hyundai in the 2015 Sonata. It supports both touchscreen and button-controlled head units.
Android Automotive is different: it is a full operating system running on the vehicle’s own hardware, so it does not need a phone. The Polestar 2 was the first car with it built in, with deliveries starting in July 2020. Volvo, Renault, Ford and GM use versions with Google services.
CarPlay Ultra, first announced on the Aston Martin DBX707 in May 2025, goes further than standard CarPlay: it can control vehicle functions and take over several screens in the car. According to Wikipedia’s CarPlay entry, it is available only in the US and Canada.
How Do Driver-Assistance Systems Use the Interface?
Advanced driver-assistance systems (ADAS) rely on the interface to warn the driver and show what the car is doing. In the European Union, the General Safety Regulation (EU) 2019/2144 has required intelligent speed assistance and driver drowsiness and attention warning on all new cars since 7 July 2024, after applying to new vehicle types from July 2022.
Automation itself is graded on the SAE J3016 scale from Level 0 (no automation) to Level 5 (full automation in all conditions). At Levels 0 to 2 a human is primarily responsible for driving. Level 3 systems can take over in defined conditions but may ask the driver to intervene. Mercedes-Benz Drive Pilot was approved for Level 3 use in Germany in December 2021, was confirmed compliant in Nevada in January 2023 and certified in California in June 2023, where Mercedes-Benz says it can operate up to 40 mph in dense freeway traffic. Readers interested in where this is heading can see how self-driving technology could help disability-friendly vehicles.
Are Touchscreens in Cars Safe?
Touchscreens are convenient but can pull a driver’s eyes off the road. In a 2017 AAA Foundation for Traffic Safety study of 30 model-year 2017 vehicles with 120 drivers aged 21 to 36, programming navigation was the most demanding task, taking an average of 40 seconds. AAA notes that looking away from the road for just two seconds doubles crash risk, and it recommended locking out text messaging, social media and navigation programming while the car is moving.
Euro NCAP has responded in its rating system. From 2026, its protocols are organized into four stages (Safe Driving, Crash Avoidance, Crash Protection and Post-Crash Safety), and cars need dedicated physical controls for indicators and hazard lights, windscreen wipers, the horn and SOS/eCall to score top marks. Five-star cars must also use driver state monitoring that tracks the driver’s eyes and head. For more on the wider risk, see this guide to the dangers of not paying attention on the road.
How to Use an In-Car Interface More Safely
- Set navigation, playlists and climate before moving off.
- Use steering-wheel buttons and physical controls for frequent tasks instead of screen menus.
- Use voice commands for calls and messages, but keep them short and avoid long dictation in heavy traffic.
- Turn on the phone’s driving or do-not-disturb mode so notifications do not pop up on the car screen.
- Learn which driver-assistance warnings your car shows, and remember that Level 2 systems still require you to supervise.
What to Look for When Buying a Car With a Modern Interface
- Phone compatibility: check whether the car supports CarPlay, Android Auto, or both, and whether the connection is wired or wireless.
- Physical controls: check for real buttons or stalks for indicators, wipers, hazard lights and climate.
- Screen layout: test how many taps common tasks take during a test drive.
- Driver assistance: confirm which systems are fitted and how warnings appear in the cluster or head-up display.
- Software support: ask the dealer how the system is updated, since features increasingly depend on software. Technology-heavy cars can also affect cover, as explained in this article on how future car technologies affect warranties.

Frequently Asked Questions
What is a vehicle user interface?
A vehicle user interface is the set of screens, buttons, voice controls and displays a driver uses to operate a car’s features. It usually includes an infotainment touchscreen, an instrument cluster, steering-wheel controls and, in some cars, a head-up display.
What is the difference between Android Auto and Android Automotive?
Android Auto mirrors apps from an Android phone onto the car’s screen and needs the phone connected. Android Automotive is a full operating system that runs on the car’s own hardware without a phone; the Polestar 2 was the first car to have it built in.
Is voice control safe while driving?
Voice control is safer than handling a phone, but it is not distraction-free. Research for the AAA Foundation for Traffic Safety found drivers could stay distracted for up to 27 seconds after using voice commands, and practice did not eliminate the effect.
Why are carmakers bringing back physical buttons?
Carmakers are bringing back physical buttons partly because of distraction concerns and partly because Euro NCAP, from 2026, requires physical controls for indicators, hazard lights, wipers, the horn and eCall/SOS to award top ratings.
Which car has a windshield-wide display?
The BMW iX3, the first Neue Klasse model, was the first BMW with Panoramic iDrive, whose Panoramic Vision display projects information across the full width of the lower windshield. Production began in October 2025.
