Why can CarPlay charge but not connect?

CarPlay can charge but not connect because the USB debugging on the phone is not enabled. Try restoring the car's infotainment system to factory settings and then reconnect to see if it works. If it still doesn't connect, you may need to visit a 4S store for inspection. CarPlay is an in-car system developed by Apple Inc., seamlessly integrating users' iOS devices and iOS experience with the dashboard system. CarPlay only supports iPhones with a Lightning interface. Although iPads also support this interface, Apple has not included iPads as hardware devices supported by CarPlay.
Hey, I often help friends troubleshoot their car infotainment issues. When CarPlay can charge but won't connect, the problem usually lies with the cable or port. Charging and data transfer use separate circuits – the cable might be damaged and only supporting charging, so check if it's an original or MFi-certified cable. Dust buildup or loose USB ports can also interfere with connections – try cleaning or gently wiggling the connector. On the software side, your iPhone or head unit might need system updates, especially since older iOS versions may lack compatibility with new features. For wireless CarPlay models, ensure both Wi-Fi and Bluetooth are enabled, and try rebooting both the head unit and phone. For prevention, keep a spare cable in your car and regularly clean the ports to avoid headaches. If problems persist, visit a professional shop to inspect the vehicle's module before it leads to costlier repairs.
I had the same issue last time I drove, and it was really annoying. CarPlay charges normally but fails to connect—most of the time, it's the cable causing trouble. I fixed it by switching to a new Apple-certified cable because the old one had a damaged data transfer part. It could also be dirt in the iPhone port affecting the connection; carefully cleaning it with a toothpick helped a lot. Another time, it was a system bug, and updating to the latest iOS version automatically resolved it. Remember not to deal with it while driving—restart the device or car system after parking. Here’s a tip: when buying cables, look for MFi-certified brands and don’t just go for the cheapest option. If the car’s USB port is damaged, repairs can cost at least a few dozen bucks, but DIY cleaning can prevent it.
As a tech enthusiast, I've researched many CarPlay issues. The common reason for being able to charge but not connect lies in data connection failure—the cable only supports power supply, try switching to a certified cable. Poor software compatibility could also be the cause: check if both your iPhone and car system are on the latest versions, as older systems may cause disconnections. Restarting the car's infotainment system, phone, or toggling airplane mode can resolve temporary bugs. For wireless CarPlay, ensure Bluetooth/Wi-Fi connectivity is smooth. On a related note, the new CarPlay's voice navigation support is very practical—make sure it's enabled in the settings.
