Vehicles that had software from ISTA-P 3.58.3 or below and upgraded to next level 3.59.0 lost seat memory gong (ie the auditory confirmation of setting seat preference). But, those with LED adaptive headlamps also got improved parameters for a smoother system. As such, upgrading is a "crapshoot" because there are no release notes indicating changes and you could gain function enhancements or lose features.




Root directory means not within any folder of USB flash drive. For example, C:\ and not C:\update. There are different drive formats (NTFS, FAT32, etc). You can right click drive and select properties so see how it is formatted. If incorrect or undesired setting, then you right click and select format to change. Formatting will erase entire drive contents so you must place files after process.

thanks a lot
