where is the 'return' v2.004.6??

hey guys i have firmware 2.004.6 now because my menu button didnt work anymore and im in some screen where it normally plays the music and i dont see the 'return' button anywhere
im stuck in that screen !!! help

Keep the enter-button (sp)/player-button (sl, ts) pressed for up to 2 minutes. This should (if Hold is off) shut down your m6 properly.
I don't quite get whyt you mean with "i don't see the return button anywhere" as the return button is on your hardware (m button) but this should solve your problem nontheless)
