Repeatedly search for and connect to VehiConn-*** (password 88888888 ) in the WiFi list; if it cannot be found, use a computer or another device to connect instead. 

After connecting, open a browser and visit 192.168.50.100 , then change the WiFi AP option to a different value. In some countries or regions, using a certain value may cause WiFi connection issues, so a different band needs to be selected.
