There is no traffic in the navigation mobile APP, and I am an Android mobile phone. Now the mobile phone is a map of Gaud, but go under the tunnel or viaduct.

You can use Tencent map. This mobile navigation has offline data packets. You can download its offline data package, turn on offline mode, and realize zero traffic navigation. Moreover, there is no need for traffic to query the route and browse the map, and the voice broadcast of Tencent map is very accurate. I have been using this navigation, which has many functions, such as real-time oil price, electronic eye, illegal inquiry, payment of fines and so on. You can also check the road information in advance before going out.
