I have just purchased an iPod Classic 160GB and I am delighted with it. Only thing is, when it is in the dock of my Jamo system, the display screen does not function. When a playlist has finished playing, I have to press "Menu" in order to bring the screen to life again. This was not the case with my previous iPod (60GB) - the display was on all the time. Can anyone tell me what to do to rectify this glitch?
