NAVIGATION SYSTEM AND METHOD, AND ELECTRONIC DEVICE

A navigation system, method and an electronic device provide for obtaining high-precision road data of a no-network-connection route segment from the server and displaying a lane-level navigation route of the no-network-connection route segment based on the high-precision road data of the no-network-connection route segment. When the electronic device moves to the no-network-connection route segment in the recommended route, the electronic device may obtain high-precision road data of a second route segment from the server and display a lane-level navigation route of the second route segment based on the high-precision road data of the second route segment. In this solution, the electronic device can quickly and accurately display a lane-level navigation route.
