USB stick is not supported

Hi,

I am new to this forum and this is my first post here. I have the Aux and USB ports in the center console. Initially I tried my friend's USB stick and it worked fine. All songs were listed and can be played. Thinking it a viable option to play my music, I bought a USB drive and copied my files on it, but when I inserted it in the USB port, it says "Connected USB is not supported".

I have compared both working and non-working USBs, both have same formatting (FAT32), files are copied in the root folder in both sticks (no subfolder created) but even then one is working and other is not. The only difference is working USB stick is 4GB while non-working is 2GB.

Can you pls suggest what is wrong here?? Any suggestion.?? pls

Just a wild hunch... Reformat the 2G drive that is not recognized.
