# CarPlay

CarPlay is an Apple standard that enables a car radio or automotive head unit to be a display and controller for an iOS device. It is available on iPhone 5 and later models running iOS 7.1 or later.
More than 800 car models support CarPlay, according to Apple. Vehicle owners can add support by installing certain aftermarket vehicle audio products.
Most CarPlay systems connect to iOS through USB, some are wireless, and wireless support can be added through aftermarket dongles.

## Software

Apple's CarPlay-enabled apps include:
* Phone
* Apple Music
* Apple Maps
* Calendar
* Messages
* Audiobooks (part of Apple Books)
* Podcasts
* Settings
* News
Developers must obtain permission from Apple to develop CarPlay-enabled apps. Such apps fall into five categories:
* Audio: primarily provide audio content, such as music or podcasts. Examples: Amazon Music, Audible, Google Play Music, iHeartRadio, QQ Music, Spotify, and Overcast.
* Navigation: turn-by-turn guidance, including searching for points of interests and navigating to a destination. Examples: AutoNavi, Baidu Maps, Google Maps, ChargeFinder and Waze.
* Automaker-made apps allow a user to control vehicle-specific features such as climate controls, gas levels, or radio via CarPlay.
* Messaging/Voice over IP (VoIP): listen to new messages and reply using dictation in an audio-only interface. Messaging apps on CarPlay integrate with third-party Siri support (known as SiriKit), while VoIP apps integrate with the iOS calling interface using CallKit. Examples: Telegram, WhatsApp, and Zoom.
* Food-ordering and parking-services apps.
To discourage distracted driving, Siri is used extensively, providing voice turn-by-turn navigation guidance and voice-input for text messages. Newscast-style weather and stock results are announced instead of displayed. Requests that bring up visual information may be blocked when the car is in gear, and most native CarPlay apps deliver audio content with minimal interaction.
CarPlay-enabled apps installed on the device appear on the CarPlay home screen unless disabled by the user. The inclusion or exclusion and order of app appearance can be changed on a per-vehicle basis.

## Hardware

Most of the CarPlay software runs on the connected iPhone, and the CarPlay interface provides the audio and display connection to the car's infotainment system. CarPlay adapts to various display sizes and control interfaces for each vehicle: touch screen, rotary dials, buttons, steering-wheel controls, and hands-free microphones.
Aftermarket head units may support CarPlay or Android Auto, usually both.
The iPhone can connect to the car either via a USB cable or wirelessly.
Wireless CarPlay works by having the phone exchange network credentials with a supporting CarPlay receiver over Bluetooth, establishing a two-way Wi-Fi connection.
Alternatively, it is possible to use a third-party dongle adapter plugged into the car infotainment system's USB port to enable a wireless connection. This still requires a car infotainment system that supports standard (wired) CarPlay.

## History
### Predecessor

In 2008, one year after the release of the iPhone, Mercedes vehicles were first to sell an audio system incorporating both the iPod and iPhone, equipped with 30-pin iOS input jacks. The new 2008 Harman Kardon NTG 2.5 featured full audio streaming, syncing, charging and control integrated into the steering wheel controls, instrument panel, and head unit. Apple was working with Mercedes to develop iOS compatible audio systems into their cars first only a year after iPhone launch. With an Apple Lightning-to-30-pin adapter, iPhones/iPods remain backwards-compatible with the Harman Kardon 2.5 and later models. This is the earliest audio system specifically engineered for iPod/iPhone integration, which predated CarPlay and every other manufacturer incorporating iOS into vehicles.
The concept of CarPlay was based on the iOS 4 feature called "iPod Out" which was produced through several years of joint development by Apple and the BMW Group's Technology Office USA. iPod Out enabled vehicles with the necessary infrastructure to "host" the analog video and audio from a supporting iOS device while receiving inputs, such as button presses and knob rotations, from a car's infotainment system, to drive the "hosted" user interface in the vehicle's built-in display. It was announced at WWDC 2010 and first shipped in BMW Group vehicles in early 2011. The BMW and Mini option was called "PlugIn" and paved the way for the first cross-OEM platforms, introducing the concept of requiring a car-specific interface for apps (as opposed to MirrorLink's simple and insufficient mirroring of what was shown on the smartphone's screen).

### Development

CarPlay's codename was Stark. Apple's Eddy Cue announced it as iOS in the Car at WWDC 2013. In January 2014, it was reported that Apple's hardware-oriented corporate culture had led to release delays. iOS in the Car was then rebranded and launched as CarPlay with significant design changes at the Geneva Motor Show in March 2014 with Ferrari, Kia, Mercedes-Benz, and Volvo among the first car manufacturers.
At WWDC 2022, Apple announced plans to release an all-new version of CarPlay, informally dubbed CarPlay 2. The new version was said to be able to control vehicle functions, access vehicle stats, and take over multiple vehicle screens. Officials said they planned to release it in late 2024 and that manufacturers that are planning to adopt the new CarPlay include: Audi, Acura, Ford, Honda, Infiniti, Jaguar, Land Rover, Lincoln, Mercedes-Benz, Nissan, Polestar, Porsche, Renault, and Volvo.
In January 2025, Apple removed the planned released date from its website.

## Competition

The Open Automotive Alliance's Android Auto is like CarPlay for Android devices. Huawei's HiCar is like CarPlay for Huawei EMUI Android and HarmonyOS devices.
Some vehicle manufacturers have their own systems for syncing the car with smartphones. Examples include BMW ConnectedDrive, NissanConnect, Hyundai Blue Link, iLane, MyFord Touch, Ford SYNC, OnStar, and Toyota Entune.
MirrorLink is a standard for car-smartphone connectivity, currently implemented in vehicles by Honda, Volkswagen, SEAT, Buick, Skoda, Mercedes-Benz, Citroën, and Smart with phones by manufacturers including Apple, HTC, Samsung, and Sony.
Tesla and Rivian's infotainment systems exclude support for CarPlay and Android Auto.
In April 2023, General Motors announced that it would gradually stop including Apple CarPlay and Android Auto in its electric vehicles so that it could collect and monetize more driver data and deliver a better user experience. Consumers criticized GM's action. The Detroit Free Press reported that some longtime GM customers said the lack of CarPlay would lead them to look at buying a Ford vehicle instead. Some press reported that the move would promote GM's partnership with Google and would cut off revenue streams to Apple at the expense of its customers. Some noted that the move would severely reduce customers' data privacy.
