What does tmc mean?
TMC is a mature vehicle intelligent traffic navigation technology in Europe, which can reflect the traffic situation in the region in real time, guide the best and fastest driving route, and improve the efficiency of roads and vehicles. So in function, TMC and other systems are the extension of GPS system application. At present, the cities opened in China mainly include Beijing, Shanghai, Guangzhou, Shenzhen, Nanjing, Chengdu, Shenyang, Ningbo, Chongqing and Tianjin.
Extended data:
Based on its working principle, TMC receives and processes information through GPS antenna and displays it in the form of navigation road conditions. As long as the GPS system is normal (that is, the navigation guidance function is normal) and the vehicle navigation settings are normal, it can be determined that the road conditions that cannot be displayed have nothing to do with the vehicle itself.
The reason why TMC information cannot be obtained is because the transmitter or signal is blocked for some reason. For example, 20 15, 10 month, so no vehicle can use this function. The receiving source of automobile TMC is different from other terminal devices such as mobile phones, so there will be cases where automobile TMC is unavailable and other terminal devices are available.
