The FAT32 format is often recommended to ensure maximum compatibility with certain systems, especially car infotainment systems, embedded devices, and BMW navigation systems.
Here is a simple and quick tutorial to help you format your USB drive correctly.
On recent versions of Windows, you will often only see NTFS and exFAT as formatting options.
This is normal: Windows no longer offers FAT32 in its default formatting tool when the USB drive exceeds 32GB.
This is a limitation imposed by Windows, not a technical limitation of FAT32 itself.
If your USB drive is 32GB or less, follow these steps:
Warning: formatting will erase all data on the USB drive.
If FAT32 does not appear, your USB drive is likely larger than 32GB.
In this case, the easiest solution is to use a third-party tool such as GUIFormat, also known as the FAT32 Format Tool.
Steps:
This method allows you to format USB drives of 64GB, 128GB or more in FAT32.
For maximum compatibility, FAT32 is often the best choice.
Warning: formatting a USB drive in FAT32 on macOS is possible, but may cause issues.
When copying files, macOS automatically creates hidden files (e.g. ._filename or .DS_Store). These invisible files can interfere with USB drive detection on your BMW or Mini. Result: the USB drive may not be recognized for installation.
To avoid any issues, it is strongly recommended to use a Windows computer to prepare your USB drive.

Note: On Mac, MS-DOS (FAT) corresponds to the FAT32 format.
For specific use cases such as vehicle systems, FAT32 remains the safest choice.
If you don’t see the FAT32 option on a recent Windows PC, this is normal.
Windows limits FAT32 for drives larger than 32GB. In this case, use a tool like GUIFormat or format via Mac using Disk Utility.
For maximum compatibility, FAT32 is usually the best choice.
