Wireless Apple CarPlay utilizes a dual-connection strategy, leveraging Bluetooth for initial pairing and subsequent reconnections, while Wi-Fi handles the active data transmission for audio, video, and control. The system establishes a direct Wi-Fi link between the iPhone and the car, independent of external internet access.
