What is the reason why the Haval car cannot connect to the internet?

Taking the 2021 Haval F7 as an example, the inability to connect to the car's internet may be due to signal issues or incompatibility between the phone and the car. Related introduction: 1. In-vehicle network standards: Currently, there are mainly two types of Class B networks in use: Low-speed CAN and VAN. The VAN standard is based on ISO11519-3 and is primarily used by French automobile companies. However, even in France, the focus is on the CAN bus for powertrain systems. 2. Introduction: The Haval F7 is the second model in the Haval F series. It serves as the flagship model of the Haval F series, an AI smart connected SUV. The new car comes in two versions: 1.5GDIT and 2.0GDIT, with a total of 6 models.

The Haval car can't connect to the internet, and I think it might be related to signal coverage. If you're driving in mountainous areas or underground parking, the signal is definitely weak; in this case, it's recommended to try changing locations. Additionally, the built-in SIM card in the car might not be activated or could be out of credit, so you need to check its status via the app or contact the provider to top up. System settings are also a common cause, such as turning off data services in the car's settings; you should check if the network switch is turned on. Outdated software versions can also lead to connection failures, so regular updates are necessary. I've helped a friend deal with a similar issue before and found that loose antenna connections are quite common, especially after long periods of bumpy rides. Safety first, it's advised to operate the settings after parking. If none of these solutions work, it's best to have a professional shop check the module.
