BMW iDrive Navigation and SD Cards
BMW’s iDrive navigation system has gone through several generations, each using a different map storage format. Getting the right SD card for your specific BMW requires knowing which navigation system you have — this guide makes that simple.
BMW Navigation System Generations
CIC (Car Information Computer)
Used in BMWs from approximately 2009–2013. CIC systems use a DVD-based navigation update rather than SD cards. If your BMW has a single-slot DVD drive in the glovebox or centre console, this is likely your system.
NBT (Next Big Thing)
Introduced around 2013. NBT systems use a navigation SD card — a full-size SD card that inserts into a slot usually located in the glovebox. This was used across the 1, 2, 3, 4, 5, 6, 7 Series and X models from 2013–2016.
NBT EVO
The updated version of NBT, introduced around 2016. NBT EVO has a larger, higher-resolution display and improved touch response. It still uses the same full-size SD card slot in the glovebox, but requires a different map version to NBT.
MGU and MGU High (2019+)
Newer BMW models from 2019 onwards use the MGU or MGU High system, which receives over-the-air map updates and does not require an SD card.
How to Check Your BMW’s Navigation System
From the iDrive menu: navigate to Navigation → Map Version. The map version code and system type will be displayed. Alternatively, go to Settings → System → Version information.
You can also check your vehicle’s build list (on the label inside the driver’s door) for the navigation option code: 609 indicates Professional Navigation (NBT), 6U3 indicates the later EVO system.
Installing the BMW Navigation SD Card
- Open the glovebox and locate the SD card slot
- Insert the navigation SD card with the label facing up
- Start the engine (or press the start button without pressing the brake to enter accessory mode)
- The iDrive screen will prompt you to begin the map update
- Accept the update and allow it to complete — do not remove the card during this process
- Update time is typically 30–60 minutes for a full map region
Important: Keep the Card Inserted
Unlike some navigation systems, BMW NBT and NBT EVO require the SD card to remain inserted during normal use — the navigation reads directly from the card. Removing the card will disable navigation until it is reinserted.
