Problems solved by technology

[0004] In this way, first of all, because the navigation data in the map update server needs to be collected, and the collection method is usually that the map manufacturer builds its own collection vehicle to collect the road conditions in each district, the collection will take a long time and the amount of data is large. The navigation data is not accurate enough, and the navigation map update effect is not good
