I returned it to the store today.. I will continue to use the a.aux and not the N.music. It would have been nice to have the box and n.music, then I could have the bluray in to the a.aux..
I will put my money on a 3500 speaker for now instead. Maybe I will try again later with the box.
If U figure out the prob, I would be very happy to hear, for the future :)
