What does the icon in iOS indicating a connection to CarPlay look like?

The icon that indicates a connection to CarPlay in iOS features a car symbol. This visual representation clearly signifies that the iPhone is connected to a vehicle's infotainment system, enabling the use of various apps and functions tailored for driving environments. The car icon is intuitive for users, as it directly relates to the automotive context of CarPlay, making it easily recognizable for those who are familiar with the technology.

In contrast, the other options represent different functionalities or features on iOS. For instance, an airplane symbol typically indicates airplane mode, which disables all wireless communications. A phone with Wi-Fi bars suggests cellular connectivity or a device's network status, while a music note generally signifies audio playback or music-related apps. These icons, while they serve important roles within iOS, do not relate to the features and functions provided by CarPlay.
