The timing of updates depends on the platform. On most online channels, such as Google, changes are visible almost in real time - often within a few minutes of input. GPS systems and car manufacturers have their own schedules, which can be monthly, quarterly or yearly. Smart cars with a continuous online connection allow faster and more frequent data refreshes.
We have no direct influence on the publication schedules, but more detailed information on the frequency of updates is available on the websites of the individual providers.
