Problems with gen4 music via USB

I'm not sure if it's using a playlist behind the scenes, which I believe may well be where the 10,000 song limit comes from as that seems common on other applications, i.e. Windows desktop programs, but I'm curious to know if others have experienced such an issue updating their USB sticks, if indeed I'm not alone in still using this old way of doing things, and if there's a cleaner way of updating/recovering from this strange situation that doesn't seemingly require me to wipe the stick completely and transfer all the music back on to it.
At least I have Planet Rock to listen to as an alternative through DAB and I don't do streaming through my phone as I'm on a pay as you go contract, which at around £20-30 a year for my usage I'm not going to start changing habits when USB should just work.

The only way I can get it to play nice, is to reformat the drive, using a bespoke tool as it's 128GB and Windows won't allow FAT32 formatting of that. Now, whenever I format the drive, it generates a new ID for it of the format nnnn:nnnn. The first time this is inserted the head unit seems to cope OK, but I don't know whether it's still limited to 10,000 files or not. Once I remove it and reinsert it, it's then that it all goes horribly wrong as I suspect it's trying to re-read data previously associated with it which may be bad due to number of files (assuming it's not just a rubbish system).
It's a bit of a pain having to reformat/regen a new ID every time I want to add to it, which I do frequently as we tend to buy music regularly and like the randomness of our whole collection on a long drive.
So, first test will be to truncate down to < 10,000 files and see if I can remove/insert at will without issue. Seems such a daft limitation but if it's using OSS playlist functionality (seems to be a lot of OSS software utilised on the head unit) then it may be an industry standard limitation, which is still rubbish. It's a real shame the unit doesn't give more flexibility on playing USB music, i.e. on the folder view, I've not found a way to play a folder, only tracks, so I can't play everything from a particular artist from folder view, only from what it's correctly scanned.
An option to rescan the USB would be good, and not uncommon on other systems...

I've just found a small utility that will allow me to change the disk serial so at least I can just copy new music onto it, run that and hopefully it will consider it a new stick each time and read the music properly. My only concern with that now is that it might be storing information per stick so I could be building up a glut of hidden files as it tries to be clever with each one.
There's a long thread on the xda-developers site about the suzuki slda head unit but it's mostly concerned with sat nav updates rather than the rest of the unit, but I've not read the whole 100+ pages of content. It's a shame really, I'm finding the head unit otherwise fine for what I need and I've always found something equally disappointing with aftermarket products.
Don't get me started on how far behind car infotainment is with general computing and the incurred cost for new technology. Why oh why there seems to have been a trend for tying in firmware updates to map updates I'll never know, other than monetise it and fleece the end user. Nearly every other electronic device I have allows free firmware updates.

I equally don't know if there's a file limit through the phone or whether it just treats it as an offboard DAC and streams the audio but using the phone. The downside for me would be plugging it in each time I get in and out whereas I currently just keep it in my pocket. I might still try that route anyway just to see how it fares once I bottom out the USB stick idiosyncrasies.
My other thing to attempt will be a playlist of all the files, but that's something else to maintain and keep adding to as we buy more music. We really shouldn't have bought, and continue to buy, so many CDs.

- when the head unit first discovers the USB stick and indexes it, it appears to discover all the music without issue, although I'm not sure if that's truly the case as some of my music in the latter reaches of the alphabet was never played. Given the large number of files, it's hard to know if this is just a random number issue with a general median in the middle reaches and the outliers being less played
- if new files are added that takes the stick > 10k files, or was the first addition following the first read, things go odd and the list of artists becomes heavily truncated, in some instances for me, down to four artists
- reducing the number of files back under the 10k limit appears to bring things back to normality
- creating playlists of the files works to a degree, but again, I've not seen anything in that latter reaches of the alphabet. In fact, in the time I've been trying this with both a .m3u and .wpl playlist, I never had anything later than the letter J, which for me is less than 6k files. Again, skipping tracks can only entertain me for so long, but I certainly expected something later
So for the time being, I'll either have to truncate my music down to those tracks I know I'd want to listen to more regularly, or look at porting it all to my mobile phone and relying on the two devices to play our music collection. It is a disappointment, my recent vehicles have all coped without issue. Maybe a future firmware update will lift the restriction, although from what I can see I'd probably have to go with a maps update just to get it and I'm not sure I'm that bothered if it's going to get expensive.
If anyone's interested, and also so I don't lose it, the script I used for generating the playlists is below. It's windows batch, so not pretty, but may be useful for people in future. My music lives in a <root>:\Music folder, then artist, album, songs arrangement and I understand that the playlists can work with relative paths, so I remove the path prefix from the file listings. There's probably an easier/better way to do it, but I was trying to get something in place to (dis)prove theories so it's served it's purpose. I stuck it in the root of my USB and ran it from there, either from a DOS prompt or by launching through the GUI.

The downside is it won't allow me to update anything, just have a nosey around some elements of the head unit.

Might be of interest how I manage my music between PC and Android mobile. My music (about a 50/50 mp3/flac mix) lives in my OneDrive folder (so replicated to the cloud with version control), with a similar structure to yours (artist/album/track). I use MediaMonkey Gold on both devices which allows me to sync my library to my phone over WiFi, no need for any manual copying. You can apply criteria to the sync process, so I typically only sync tracks that I've given a 4 or 5 star rating, which lets me keep all of the more obscure stuff at home and have the tracks are currently flavour of the month on my phone.
For in-car playback I use Bluetooth for shorter journeys, keeping my phone in my pocket and via cable and Android Auto for longer trips.

For home use it's all converted down to AAC, hangover from us using ipods in the car, but now all held on a sony walkman connected to the home stereo. Other than that I have it replicated on three USB sticks, one for the missus, one for each of my cars and for my daily car I dump it on my secondary drive at work.
Like you, all mine is managed through media monkey, again, hangover days from when we had ipods (which we still have, just don't use them anymore).
The downside is we probably buy two or three new albums a month on average, so I end up building up another glut to rip, store and convert.
I probably have the dumbest smart phone in that I use it for calls, texts and photos, nothing else. We're both on pay as you go so keep data to a minimum as/when we need to and a battery charge will last me a good week through lack of use, but available if I need it.
I could put all the music on my phone and sync to that in both cars, well probably the missus' as well (but then I get control ). I've actually enough space on there too, in lossy format there's about 75GB of data, about 600GB or so in lossless I think. Both of us like the whole library with us, on random, just because it covers so many bases and we never know what's next. Even music that we don't particularly like, more me with some of the missus' taste, I'll at least give another go when it comes on randomly.
To give a minor update, I raised a query with Suzuki customer services and they agreed to pass on my issue to Bosch as a defect/feature enhancement request. They also fed back that we'll be entitled to free firmware updates, but only through the dealer when we take the car in. They'll allegedly check if we need an update and put one on, or do that on request, so it's not actually tied to the map update, but they also went let us do it ourselves.
Maybe it's time to start filling my phone with music...
