Unknown nano clone mp3/4 player

[Luke]

Hi

I bought a mp3/4 player and want to know a few things about it.
looked around on the site but couldn't find one that looks the same.
It came with an ipod nano box and features guide who look original. the player has the appel logo on the backside. But the cd than came with the player doesn't work. every icon i click on doesn't work. on the back it says 4G and firmware is:
3.5.35
jtymd046v4


on the front it looks like this.

Menu=above
play/pause/stop= mid center
backward/previous= mid left
forward/next= mid right
A-B/Rec= under

does anyone know what player this is and where i can get the tools i need. and how i can put on new themes?

I hope someone can help me.
