Apple CarPlay is not a standalone gadget but rather a software platform developed by Apple that integrates with your car\s infotainment system. It allows you to connect your iPhone to your car\s display, providing access to various iPhone features and apps in a simplified and safer manner while driving. While CarPlay itself isn\t a physical gadget, you may need a compatible car stereo system or head unit to use it in your vehicle. Once connected, you can use CarPlay to navigate with Apple Maps, make calls, send and receive messages, listen to music, and use other supported apps—all through your car\s display.
