CarPlay is Apple's in-vehicle projection system. An iPhone connected to a compatible car runs the software and sends a simplified, driver-oriented interface to the vehicle's built-in screen, where maps, music, podcasts, messages and calls can be controlled by touch, by the car's knobs and buttons, or by Siri. The car supplies the display, speakers and controls; the phone supplies the apps, data and processing. Apple introduced it on March 3, 2014, at the Geneva Motor Show, as an answer to dashboard software that aged badly and could not match the phone already in the driver's pocket. According to Apple's own listing, CarPlay is offered on "more than 800 models" from more than 80 manufacturer entries, as of October 2026.

How the connection works

CarPlay runs over two kinds of link. The original method is wired: the iPhone plugs into a USB port, and the car recognises it as a CarPlay device. The wireless method, supported since iOS 9 and first offered by BMW in the 2017 5 Series sedan announced on October 13, 2016, layers two protocols. According to research published by security firm Oligo on September 9, 2025, the phone and car first talk over Bluetooth using Apple's iAP2 accessory protocol, which authenticates the head unit and hands the phone the car's Wi-Fi network name and password. The iPhone then joins that Wi-Fi network and streams the CarPlay screen to the car over AirPlay, the same technology used to send video to an Apple TV.

The car's infotainment unit does not run CarPlay apps. It displays a video stream rendered on the phone and sends touch, knob and steering-wheel input back. Automakers and their head-unit suppliers integrate Apple's software components, including the AirPlay audio and video software development kits (SDKs) and a CarPlay communication plug-in, into their own systems. When the phone leaves, CarPlay disappears with it. As PPC Land put it when Apple won a navigation deal with Ford, without a phone the maps disappear.

App categories and entitlements

Third-party apps cannot simply appear on a CarPlay screen. A developer must apply to Apple for a CarPlay entitlement, a permission tied to one category of app, and agree to a CarPlay Entitlement Addendum. Apple reviews the request and, if approved, assigns the entitlement to the developer account. According to the CarPlay Developer Guide, October 2026 edition, the categories are: audio, communication (messaging and voice calls), driving task, EV charging, fuelling, navigation, parking, public safety, quick food ordering, video, and voice-based conversational apps. Apps may hold only one category, with the exception that EV charging and fuelling can be combined.

Navigation apps date from iOS 12, released in 2018, when Google Maps and Waze could first appear. Audio, communication, EV charging, parking, public safety and quick food ordering require iOS 14. Driving task and fuelling arrived with iOS 16, voice-based conversational apps with iOS 26.4, and video with iOS 27.

Except for navigation apps, which draw their own maps, third-party apps do not design screens. They fill templates supplied by Apple: lists, grids, tab bars, a now-playing screen, point-of-interest maps and a handful of others. The limits are deliberately tight. Some cars cap lists at 12 items, grids allow eight choices, and a point-of-interest template shows up to 12 locations. Template hierarchies can be at most five screens deep for audio or navigation apps and three for fuelling. Driving task apps may not refresh data more than once every 10 seconds and may not act as store finders. No brand controls the layout.

Origin and evolution

Apple first described the idea as "iOS in the Car" at its developer conference in June 2013. At launch in March 2014, Ferrari, Mercedes-Benz and Volvo were named as the first automakers to ship it, with BMW, Ford, GM and Jaguar Land Rover among those committed. It shipped as part of iOS 7.1.

Later releases widened the product: wireless connections from iOS 9, third-party navigation in iOS 12, a split-screen Dashboard view in iOS 13, and new app categories in iOS 14 and iOS 16. At WWDC in June 2022, Apple previewed a next-generation version that would take over every screen in the car, including the instrument cluster, and listed at least 14 automakers as supporters, according to reporting by Tom's Guide. That product was renamed CarPlay Ultra and began rolling out on May 15, 2025, in Aston Martin vehicles in the US and Canada. It requires an iPhone 12 or later and iOS 18.5. Apple said Hyundai, Kia and Genesis had also committed.

Why it matters for marketers

CarPlay sits between advertisers and one of the few places where media consumption is still long and largely uninterrupted. According to a 2025 Gracenote survey of 4,001 drivers in four countries, 60% consider infotainment critical to a purchase and 42% spend four or more hours a week in their vehicles. McKinsey research reported by 9to5Mac in June 2024 found that 38% of US buyers of petrol cars would not buy a vehicle without CarPlay.

For audio, CarPlay is a distribution channel rather than an ad format. Podcasts, streaming music and radio apps carry their own ads into the car, and Edison Research data on listening settings, cited when Apple opened Podcasts to video, includes commuting via CarPlay. Competitors in the dashboard pursue the same audience directly: SiriusXM launched an ad-supported tier aimed at about 100 million vehicles in July 2025, and LiveOne has bet on connected-car streaming.

The second angle is local search. Apple Maps runs on CarPlay, and on August 21, 2026, Apple Maps ads went live in the US and Canada, following an announcement on March 24, 2026, that Maps was getting ads. Apple has not said publicly whether those ads appear on the CarPlay screen. Whoever controls the dashboard map controls which charger or restaurant a driver sees.

Limitations and disputes

The sharpest dispute is with automakers. On March 31, 2023, General Motors said it would drop CarPlay and Android Auto from its electric vehicles, starting with the 2024 Chevrolet Blazer EV, in favour of a built-in system based on Google software. GM argued that a native system could, for example, precondition the battery when the driver navigates to a charger, something a projected map cannot tell the car to do. Reuters noted the change could also help GM capture more driving and charging data. In October 2025, chief executive Mary Barra told The Verge's Decoder podcast that the phase-out would extend to petrol vehicles as well, tied to a new computing platform due in 2028.

CarPlay Ultra has met similar resistance. Mercedes-Benz abandoned its plans in April 2024, and in June 2025 the Financial Times reported that Audi, Volvo, Polestar and Renault had also stepped back. An unnamed Renault executive told the newspaper: "Don't try to invade our own systems." Ford chief executive Jim Farley said in September 2025: "We don't like the execution in round 1 of Ultra, but we're very committed to Apple."

CarPlay's quality also depends on cables, Bluetooth pairing and Wi-Fi. Video has been blocked or restricted to parked use, and video on rival systems remains contested for liability reasons. Security is a further concern: a stack buffer overflow in the AirPlay SDK, catalogued as CVE-2025-24132 and patched by Apple on April 29, 2025, allowed remote code execution on vulnerable head units. Oligo reported in September 2025 that no carmaker had yet shipped the fix. Finally, regulation shapes the feature set: MacRumors reported that the new Siri in CarPlay under iOS 27 is unavailable in the European Union at launch, which Apple attributes to the Digital Markets Act.

Not the same as

Android Auto is Google's equivalent projection system for Android phones, announced at Google I/O in 2014 and first shipped in the 2015 Hyundai Sonata. Google's control over which apps it admits has been tested in court: in Case C-233/23, the EU Court of Justice ruled in February 2025 that refusing to make the platform work with Enel X's JuicePass charging app could be an abuse of dominance, after the Advocate General reached the same view in September 2024.

Android Automotive OS, marketed as cars with Google built-in, is a full operating system running on the car itself, first shipped in the Polestar 2 in 2020. No phone is required. It is the system GM is adopting, and the one into which Gemini began replacing Google Assistant on April 30, 2026.

CarPlay Ultra is the extended version of CarPlay that also drives the instrument cluster and vehicle controls. Standard CarPlay occupies only the central screen.

Embedded Apple Maps, delivered through Apple's MapKit for Automotive SDK, runs on the car's own computer without a phone. It is separate from CarPlay, which Ford said will remain available alongside it.

Recent developments

Apple announced the iOS 27 changes to CarPlay on June 8, 2026, and MacRumors reported the release on September 14, 2026. Apps that support AirPlay video can now play on the car's screen, but only while the vehicle is parked and only in models whose makers certify the feature.

On July 23, 2026, Apple and Ford announced that Apple Maps would be built into Ford's Universal Electric Vehicle Platform from 2027, through software that runs on the car's own computer rather than on a phone. In August 2026, Autio became one of a growing number of media apps embedded directly in Ford and Lincoln dashboards rather than reaching them through projection. Apple published the October 2026 edition of its CarPlay Developer Guide yesterday, listing video as a full app category.

Summary

Who: Apple develops CarPlay; automakers and head-unit suppliers integrate it; app developers build for it under Apple-approved entitlements. Google runs the rival Android Auto and Android Automotive OS, while GM, Mercedes-Benz, Renault and others have pulled back from Apple's deeper integration.

What: A projection system that runs apps on an iPhone and displays a restricted, template-based interface on the car's screen, controlled by touch, physical controls or Siri. CarPlay Ultra extends it to the instrument cluster and vehicle controls.

When: Previewed in June 2013, launched March 3, 2014, made wireless from iOS 9, expanded through iOS 12, 14 and 16, extended as CarPlay Ultra on May 15, 2025, and opened to parked video with iOS 27 in 2026.

Where: In more than 800 car models, according to Apple, with CarPlay Ultra first available in the US and Canada; some iOS 27 CarPlay features are withheld in the European Union.

Why: It gives drivers a familiar, regularly updated phone interface in place of slower dashboard software, while giving Apple a position in the car. For marketers, it shapes how audio, podcasts and local search reach drivers, and it sits at the centre of a contest between Apple, Google and automakers over who controls the dashboard and its data.
