Does CarPlay require connection to the car's WiFi?

CarPlay requires connection to the car's WiFi. The relevant introduction of CarPlay is as follows: Introduction 1: CarPlay is an in-car system released by Apple Inc. in the United States, which seamlessly integrates users' iOS devices, iOS usage experience with the dashboard system. Introduction 2: CarPlay only supports iPhone models with a Lightning interface. Although the iPad already supports this interface, Apple has not listed the iPad as a hardware device supported by CarPlay. There are mainly three ways to control CarPlay: Siri, touch screen display, and physical buttons.
No, you actually don’t need to specifically connect to the car’s Wi-Fi to use CarPlay. I’ve read many reviews and user guides, and CarPlay mainly connects in two ways: one is by directly plugging in a data cable to the car’s port, such as an iPhone’s Lightning cable—this way, the signal travels through a wired channel, which is fast and stable, completely independent of any network; the other is via wireless connection, where it first pairs your phone and the car’s system via Bluetooth, then automatically creates a private Wi-Fi hotspot between the devices for data transfer. However, this hotspot is temporary and should not be confused with the car’s public Wi-Fi. The car’s Wi-Fi is meant to provide internet access for the entire vehicle, such as navigation data that can run directly on your phone’s mobile data, without affecting CarPlay’s basic functions. I recommend starting with the wired connection to avoid complications. For wireless, the setup is simple—just tap to pair. However, be careful not to adjust settings while driving; safety comes first. If you can’t connect, restarting your phone or the car’s system usually helps.
I've been using CarPlay for several years, and it works perfectly fine without ever turning on the car's Wi-Fi. The principle is actually quite simple: wired connection works instantly once plugged in, just like charging; wireless connection relies on the car's Bluetooth to detect the phone, then automatically creates a temporary Wi-Fi network in the background. Data comes from the phone's mobile data or cache, so there's no need to connect to the car's Wi-Fi hotspot separately. The car's Wi-Fi is usually for passengers to access the internet and has nothing to do with CarPlay's screen operation. I prefer the wireless version—my phone connects automatically when I get in the car, and playing music or using navigation is smooth as butter. Just remember to park when setting up a new pairing to ensure stable signals, otherwise occasional dropouts can be annoying. For daily use, I recommend turning off auto-updates to save data—battery life isn't much of an issue. It's designed for convenience, so don't overthink it. The car's Wi-Fi toggle is entirely up to you.
