What are the reasons for CarPlay not responding when connected via a data cable?
2 Answers
Here are the specific reasons why the CarPlay data cable connection fails: 1. Check for any damage to the data cable: Inspect the phone data cable for any signs of damage or breakage, and check if there are any foreign objects attached to the metal contacts or signs of oxidation on the surface of the USB plug and the phone plug. 2. Check if the port is damaged: Examine the internal condition of the external USB and HUB female ports on the car's head unit for any damage, and ensure the contact metal strips maintain good contact with the USB male plug. 3. Check for looseness: Inspect whether there is any looseness in the connection between the car's head unit and the external USB-HUB. To prevent prolonged oxidation that may cause poor internal contact, repeatedly plug and unplug the connectors at both ends of the cable.
CarPlay connection issues can be really frustrating. I encountered this problem before. The first thing to suspect is the data cable – poor-quality cables often have connection problems, so it's best to use an original or MFi-certified one. Another possibility is dust accumulation in the phone's port; cleaning it with a cotton swab wrapped around a toothpick can show immediate results. The car's infotainment system might also act up – if the system hasn't been updated for too long, it may stop working. My older unit started working fine after a firmware update. Also, make sure both Siri and CarPlay are enabled in the settings, as system updates sometimes automatically turn them off. Finally, check the voltage of the vehicle's USB port by testing if it can read a USB flash drive. If not, you'll need to visit a service station to check the wiring.
