Why does CarPlay only charge but not respond?

[DeLyla]

CarPlay only charging but not responding could be due to the following reasons: Reason 1: USB debugging is not enabled on the phone. Solution: Restore the phone 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. Reason 2: The phone's data cable might be damaged or broken. Foreign objects or surface oxidation on the data cable plug or USB plug can also affect CarPlay connection. Solution: Replace the phone's data cable and clean any foreign objects. Reason 3: The contact metal strips in the vehicle's external USB port may not maintain good contact with the USB. Long-term use of the host's USB port can cause loosening, and over time, oxidation may occur, leading to poor internal plug contact. Solution: In this case, try plugging and unplugging the cable's connectors several times. If the issue persists, the USB port may need to be replaced. Reason 4: There might be an issue with the vehicle's host system. Solution: Restore the vehicle's host system to factory settings. Note that before restoring, ensure to back up important system information to avoid file loss during the process. Reason 5: There could be a problem with CarPlay on the phone. Solution: Turn off the phone and then turn it back on to try again. CarPlay is an in-car system released 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 now support this interface, Apple has not included iPads as CarPlay-supported hardware devices.
