Currently, NUNAV Navigation does not offer the possibility to load map material onto the device and save it there. The navigation processes real-time data in order to provide each user of our collaborative routing with the fastest and most individual route.
To ensure that you always have the latest map data available, NUNAV Navigation does not use offline maps, but adapts the map data used individually to your user behaviour.
At the moment, NUNAV navigation uses a so-called "environment caching". This means that only the environment data of your last destinations are stored. After the maximum capacity of 200 MB has been exceeded, the environment data of the "least visited destinations" are released for the environment data of new destinations. In this way, you only load the map material that you really need and can always navigate with the current map at the same time.
Due to this "environment caching", the data consumption for shorter or recurring routes (for example your way to work) is of course significantly lower than if you drive from Hamburg to Munich today and from Munich to Berlin tomorrow. On these routes, NUNAV naturally loads more real-time data, as more map material is required.
However, complete offline use will not be possible, as this would be contrary to our approach of networked driving. You can find more information about "Collaborative Routing" here.
