2014 Volvo FH - error reading usb/ipod

Hi,

So I got myself a 2014 Volvo FH .
It does have bluetooth but only for calls, no audio/music.

Previous driver had left 16G USB stick into usb/ipod port.It worked, it played music.

I took USB stick out, put it to my computer (windows 10) and formated as FAT32.

Now when I connect it to trucks usb port it says “Error reading USB/iPod”.
Tried creating smaller partition, tried to format FAT32 with different Allocation Unit Size.

nothing… wont work… but this very same usb stick worked, saw and heard it with my own eyes/ears when I took over the truck.

Anyone, any help ?
