Pen drive problem - JVC stereo

[axes2t2]

I bought a 4gb HP pen drive to plug in to the JVC panel and play music.

It worked at first but after transferring some files and formatting it is not being detected by the player.

Anyone know why ?

I guess, you've formatted as NTFS. Some stereo's cant play NTFS-formatted USBs i guess.
Try with FAT32/

Didn't work.

Also tried it in Fat file system.Only thing remaining is the exFAT.

Should I try that ?
