Non-approved USB flash drive.
To ensure error-free downloads/data transfer, the "Dealer 64 GB USB flash drive, empty, for COMAND map updates" must be used.
Can be ordered under the number A177 827 66 00
Note: It is recommended that two USB flash drives are ordered, so that one drive can be left with the specially set-up standard formatting [=FAT32, not usually available for drives of this size] and the other drive can be formatted to the NTFS file format.
If intending to re-format from NTFS back to FAT32, bear in mind that in Windows, this is only possible up to a file size of 32 GB.
