What is the reason for the Haval F7x's network connection failure?

[McKatherine]

Restore the multimedia system. If the issue persists, check whether the driver's card in use has an overdue payment problem, as these are usually the two main causes. This situation may also indicate a fault in the vehicle's comfort control unit, which triggers the yellow triangle warning icon. Try turning off and restarting the vehicle. If that doesn't work, use a computer to check for any fault codes in the multimedia system, clear them, or upgrade the system. In the Haval F7x's system settings interface, tap the [Network] button at the top to switch to the network settings screen. There are several methods to connect a smartphone to the Haval F7X: In the network settings interface, set the [Phone Interconnection Method] to [USB] or [WiFi]. Download and install the mobile app on your smartphone. USB Connection: Connect the phone to the car's USB1 port using a USB cable. WiFi Connection: Connect the system to the phone's personal hotspot via WiFi. (It is recommended to use a 5GHz WiFi band.) In the menu bar, tap the [Phone Interconnection] button and follow the on-screen instructions to complete the connection.
