Why is there no network on the car's central control screen?

When the car's central control screen has no network, it could be due to the navigation device lacking WiFi functionality or a network connection error. Check if the network is available. Below is an introduction to the car's central control system: 1. Introduction: The car's central control is where comfort and entertainment devices such as the air conditioning and audio system are controlled. It includes the central door lock system, allowing the driver to control the opening and closing of all doors and the window lifting system. 2. Central Lock: The central door lock system mainly has three functions: central control, speed control, and individual control. The driver can control all door locks, and when the vehicle reaches a certain speed, the doors automatically lock. Other doors have independent switches, allowing individual control of each door.
I've recently encountered this issue too—it's quite a headache when the car's infotainment system loses internet. The most common causes are either the data plan running out or poor SIM card contact, similar to a mobile phone being out of credit. If the vehicle is in an underground parking lot or remote mountainous areas, poor signal coverage can also lead to disconnection. Additionally, if the infotainment system hasn't been updated for a long time, or if the flight mode switch is accidentally toggled, it can disrupt the connection. Another possibility is the overheating and crashing of the onboard communication module—turning off the engine, locking the car, and waiting ten minutes before restarting might resolve it. I recommend first checking the network status in the infotainment settings and manually toggling the mobile data once to see if that helps.
