What is Prioritize offline maps mode?

In Prioritize offline maps mode, offline maps are preferentially used during base map loading, route planning, and navigation.

You can use this mode by enabling Prioritize offline maps on the Offline maps screen. When your device accesses the Internet over a cellular network and offline data has been downloaded, the offline map data will be preferentially used to provide mapping services, which helps reduce your mobile data consumption.

When your device accesses the Internet over a Wi-Fi network, the online map data will still be used by default to ensure an optimal experience.

If your device is not connected to the Internet, but you've downloaded the offline map data in advance, you can depend on the offline maps to help find your way.
