What are the reasons why the Axela cannot connect to CarPlay?

The reasons why the Axela cannot connect to CarPlay may include issues with the phone data cable, USB port problems, or connection problems between the car's main unit and the external USB hub. Solutions for CarPlay issues: Check the phone data cable for any damage or breaks, and inspect the metal contact terminals on both the USB plug and the phone plug for any foreign objects or oxidation. Examine the internal condition of the USB female port on the car's external USB hub for any damage and ensure the contact metal pieces maintain good contact with the USB male plug. Check for any loose connections between the car's main unit and the external USB hub. To avoid poor contact due to prolonged oxidation, repeatedly plug and unplug the connectors. Reset the car's main unit system to factory settings, ensuring to back up and transfer any important system information beforehand to prevent data loss. Restart the iPhone and reconnect it. Solutions for phone issues: If the above steps do not resolve the issue, insert a USB drive containing songs or videos into the USB hub to see if data can be read. If data is readable, the issue lies with the phone. If not, connect the USB drive directly to the main unit using an adapter. If data is readable then, the USB hub is faulty. If data still cannot be read, the system's main unit is faulty.

I often commute by car and encounter CarPlay connection issues with my Mazda3. Most of the time, it's due to the data cable. Not all USB cables are compatible; you need an Apple-certified one, otherwise the signal transmission will be unstable. Dust or damage in the USB port is also a common cause—try cleaning it with a cotton swab. If your phone is locked or CarPlay settings are accidentally turned off, that can also cause problems. Restarting both your phone and the vehicle usually fixes it. Additionally, outdated vehicle system software can affect the connection, so regular updates can prevent this. It's annoying but quick to resolve—don’t rush to spend money on repairs; try switching to a better cable first to see if it helps.
