@Rifleman . I have had almost a year of waiting for delivery of our Superb (she is called Rosie) and almost another year of research. As a result, my AI Assistant is well versed in all matters 'Skoda Superb' and has been trained, through memory updates, to be objective, thorough, evidence based, disagree, challenge and always tell me what I need to know, not what I want to hear. It sometimes slips up but has been getting progressively better over time. Here is the answer to your questions about the Superb's sound system which I shared with it earlier. I hope it helps. As an aside, I suspect Skoda UK Customer Services are little different from any of the other manufacturers and I also doubt the dealership wouldhave any deep knowledge unless you stumbled across an atypical employee. Yes — and the answer is considerably less restrictive than the older Škoda systems made us fear. For Rosie’s current-generation infotainment, I would set the PNY up as follows: USB filesystem: exFAT. That is the safest choice. Škoda itself specifies exFAT for modern USB media used with its current infotainment systems, including 64 GB+ media. � updateportal.skoda-auto.com Partitioning: one normal partition. There is no advantage in dividing the stick into several partitions. Audio format: FLAC is natively supported by this generation of VW Group infotainment; there is no need to convert your lossless library to MP3. Current-generation VW infotainment documentation also lists FLAC among the supported audio types. � My Car User Manual Folder structure: nothing exotic is required. I would use the very conventional Artist → Album → 01 Track.flac → 02 Track.flac etc. The infotainment can browse the actual USB folder structure as well as building its own artist/album/track database from the embedded metadata. � Volkswagen Ireland +1 Stick capacity: your 256 GB PNY is absolutely fine. Importantly, actual Mk4 Superb owners have successfully used 256 GB and 1 TB drives, with one owner specifically reporting both a 1 TB and 256 GB drive being read without difficulty. � Briskoda Library size: I cannot find a Škoda-published hard maximum for the Mk4 Superb such as “x folders/xx,xxx tracks”, so I would not quote an invented limit on Briskoda. The empirical evidence that 1 TB devices work is far more useful. Very large libraries can simply take longer to index initially; that has been reported on contemporary VW Group systems with 10,000+ tracks. � Briskoda There is one important distinction here. The 256 GB size of the stick and the size of an individual FLAC file are not problems when using exFAT. FAT32 has the old 4 GB-per-file restriction; exFAT removes that. No normal music FLAC would approach 4 GB anyway. What I would actually do with ours I would format the PNY exFAT, probably with Windows' default allocation-unit setting, give it a sensible volume name such as ROSIE MUSIC, and copy the library across in this form: ROSIE MUSIC │ ├── ABBA │ ├── Arrival │ │ ├── 01 When I Kissed The Teacher.flac │ │ ├── 02 Dancing Queen.flac │ │ └── ... │ └── The Visitors │ ├── Beethoven │ ├── Symphony No. 5 │ └── Symphony No. 9 │ ├── Fleetwood Mac │ └── Rumours │ └── ... More important than the folder names is having good FLAC tags — Artist, Album, Track Number, Title, Disc Number and preferably embedded album artwork. The infotainment's media database will then give you a much more civilised Artist/Album browsing experience rather than making you work through folders. And this confirms something from our old discussion: the PNY 256 GB stick was a sound purchase. In fact, it is rather nicely judged — enough capacity for a very substantial lossless collection without going to the rather absurd 1 TB extreme that the system apparently will nevertheless tolerate. � Briskoda If you show me the exact wording of the owner's question in the attachment, I can also tell you whether there is any wrinkle in it that I haven't covered above Best wishes, David.
