Not applicable.
Service
1. Contact TAC to receive a download link with instructions for the current MIB3 navigation database.
2. Avoid using IE (Internet Explorer) and download both files from the download link provided by TAC. Select “
download folder”, and then go to the PC “C drive”.
3. Find the 32GB USB drive, right-click the USB icon, select format, and then select “NTFS” (if the drive is formatted
in FAT32, it might not be possible to update the vehicle via the customer update menu).
4. Formatting the USB drive erases all files on the drive.
5. Open 7-zip (available at www.7zip.org if needed) and locate the NAV files on the C drive and select both files,
then click the extract icon.
6. Once the files are extracted, open the new folder. It should contain at least the folders “Data” and “Meta”. In
addition, some other files may be present.
7. Open the USB drive that was formatted to NTFS and copy the files as listed above directly to the drive (they
CANNOT be in a single folder but just as they are displayed above).
8. Eject the USB drive.
