Why can't the Great Wall Pao car networking be opened?

Here are the reasons why the Great Wall Pao car networking cannot be opened: 1. Network error: Check the network status of the car's SIM card. If the internet function of the SIM card is restricted, the car networking cannot connect, and the network naturally cannot be opened. 2. Head unit damage: If there are no issues with the network connection, the head unit might be damaged and needs replacement. Below is an introduction to the features of car networking: 1. Universality: Car networking applications are highly universal. To ensure that different car models can enjoy the convenience brought by car networking applications, these applications are designed to be universal and can provide services for various vehicle types. 2. Intelligence: The services provided are more intelligent, such as online map navigation, which can provide real-time road conditions, including traffic congestion and ongoing construction. Additionally, intelligent car networking is also reflected in its monitoring of the car itself. 3. Personalization: It can collect data on the car's driving behavior during operation. This data can be analyzed to understand the driver's habits and provide more personalized services based on this information. 4. Entertainment: It integrates the convenience of the internet with car driving.

I also encountered the issue of the car internet not working with my Great Wall Pao purchased last year. During a self-drive trip in the mountains, I couldn't connect no matter what. Later, I realized the signal was blocked by the mountain when parked near a tunnel, preventing the built-in 4G module from receiving base station signals. After driving about five kilometers to an open area, it worked normally again—the infotainment system requires real-time internet connection to verify account information. Remember to check if the antenna near the windshield is covered by sunshade film; metallic films can severely impact signal reception. I ultimately resolved the issue by switching to non-metallic window film. During regular maintenance, it's advisable to use a diagnostic tool to read fault codes to rule out hardware issues with the onboard communication module, as such parts can cost around a thousand yuan.
