What are the reasons why Buick CarPlay cannot connect?

[NicoleAnn]

The reasons why Buick CarPlay cannot connect are as follows: 1. Check whether the mobile phone data cable is damaged or broken, and whether there are foreign objects attached to the metal contact terminals on the USB plug and the mobile phone plug or whether the surface is oxidized. 2. Check whether the USB female port inside the external USB-HUB of the car host is damaged, and whether the contact metal piece can maintain good contact with the USB male head. 3. Check whether the connection between the car host and the external USB-HUB is loose. To avoid poor contact inside the plug caused by long-term oxidation, you can repeatedly plug and unplug the two plugs of the wiring. 4. Restore the car host system to factory settings. Before restoring the factory settings, be sure to back up and transfer the important information saved in the system to prevent loss during restoration. 5. Restart the mobile phone and try plugging it in again.
