Thanks for your reply.
I have contacted the supplier, but as I have to return it to the UK from Cyprus, it is hassle & cost that I didn't really need.
I have updated the library maybe 30 times now, it just won't register more than about 900 tracks under 'songs'.
I don't use it by artist so I don't know if all the 6,000 songs show up there but I very much doubt it if it is only registering about 900 songs under 'songs'...…I am hesitant to check this out as every time I go to folder view and try to browse, the unit locks up and I have to remove the card and restart it and then rebuild the music library again.
When I plug the X5 into the computer as a USB, the tracks all show up, so they are there. Also, if play them from the card on the computer all is fine and they are all there.
Also, when I plug in a USB stick with songs on it using the OTG cable and browse, it says there are no songs when for sure there are, so that facility doesn't seem to work either.
The firmware is the latest version.
At the moment, my instinct is to get a refund and return to using my 160gb Pod classic…the quality might not be the same, but it works straight from the box, the UI is significantly better and I can see the screen without needing a magnifying glass.
Sorry, but I am not impressed thus far.
