I did the upgrade on my 2019 Alltrack SE. This car has the newer 8-inch screen head unit. After programming it to 60, the mids and treble were harsh, as others reported, and 57 was boomy with recessed vocals. I think there is a lot of confusion about the 97 & 98 files, described as "2.0 reduced power", but it occurred to me that "2.0" probably meant the newer head unit. I tried it and like Goldilocks and the Three Bears, this one was j-u-u-st right! The sound is now perfectly punchy and spectacular. I'm glad I bought a programming unit because I'm the type of person who usually agonizes over the menu at a restaurant before ordering the wrong thing, and I would have been stuck in EQ hell with 60. I now have the EQ flat the way I like it.
Hope this helps, and by the way if anyone is in the NY metro area and needs to use the dongle let me know. I'll probably have it for a few more weeks.
