Hi folks

Bit of an odd one - I have the standard Skoda stereo in my 2011 car - Bolero I think, with an SD card slot. I've had about 600 songs on a 32GB SD card (formatted FAT32) which has worked fine for a year or so. The other day I took out the SD card, put 5 or 10 new MP3s onto it, and put it back in again. Stereo powered up when the card inserted, and scanned the SD card - but the 10 new songs don't appear on it, just the original 600 or so. I can see the new MP3s on the card via Explorer on my PC, but the car stereo doesn't seem to recognise them. I've Googled and looked on here, but only get results about SD cards not being recognised at all, not just that the index of the songs on the card doesn't seem to update when loaded into the stereo.

Does anyone have any ideas? I suppose I could format the card and start again. Or reset the stereo (by holding the power button down for 10 seconds I think?) but don't really see why this would help, and don't want to break something else by doing so!

Cheers.

Car is a Skoda Octavia Scout, if it makes a difference. Think my signature used to say that, but it appears to have vanished.

Are the new songs/files the same format as the original ones on sd card? Maybe you saved them in a format that the radio cant reckognise or something happened during transfer. Can you play them on your PC?

Yeah, same format, same bitrate, shorter filenames than some that play fine in the car. And the new files play fine on my PC and phone, so I'm baffled!

Thats a weird one. Try deleting some you dont listen to in case theres a limit to the number of files the radio can read. Long shot I know. I did also read that some older radios cant read more than 32GB but your sd card is 32gb so should be ok.

It may depend upon the source of the original MP3, Some car systems will not play tracks with DRM in the meta data

Suppose that may be it, but I've got other MP3s from the same (or at least very similar) sources that play fine. Nowhere near track number limit (4000 I read somewhere) or card capacity limit.

Still baffled!

when you look at the structure of the files on the sd card using your pc are they in the same folder as the tracks you can see in the car or outside it

They're all in a single flat folder, in the root of the SD card. Maybe I'll stick a few into a folder and see if that makes the stereo notice the difference!

Thanks for the suggestions, all.

Well, I copied the new files into a new folder on the sd card. They play fine from there in the car!! But it still won't recognise the same files that are still in the root of the sd card. 🤷‍♂️

If I remember correctly there's a limit to how many files in a single folder the Bolero can handle, as well as the overall track limit.

I did Google this, and the internet suggested the limit was several thousand... 4000 I think 🤔
