In some areas, up to 40% of the road network can change from one year to the next. New roads are being built, old roads are being closed or rerouted, two-way streets are being turned into one-way streets. Part of the reason is the fact that roads are always changing. Why update your navigation maps for 2020? If it's more than a year old, it's time to update. You will see the region, map version and year of your current map. To check the map version in your BMW, go to your iDrive navigation view, open the settings menu and scroll down to Navigation system version. In fact, BMW recommend updating your navigation system's maps twice a year, or annually at the very least. Whether updating your iDrive software or doing a BMW map download to the factory navigation system, keeping your BMW's iDrive up-to-date should be a regular task, just like maintaining any other part of your vehicle. But to keep a modern, iDrive-toting BMW at its best, there's a little more to it. There was a time when regular oil changes and a new set of tires once in a while was all the routine maintenance a vehicle needed.
