Pioneer docking station incompatibility
My 5th gen ipod (system 1.3 which up-to-date iTunes claims is up-to-date, tried resetting/restoring/all that), when plugged into the docking bay, pauses the music and shows a tick mark after a while with the text "ok to disconnect" beneath it. The tick mark becomes a Pioneer logo after a while but that does not change the fact that the ipod does not react, neither to the command buttons on the Pioneer system (or on the remote control) nor to the buttons on the iPod itself (those do 'click', but have no effect). It does get charged, but doesn't play, just as in the top posting.
A friend's iPod nano works just fine on the Pioneer, and my iPod works fine for everything else (headphones, iTunes, other docking systems I tried at friends', ...). So there seems to be a specific incompatibility with Pioneer systems.
How can this problem be investigated and solved ? Thanks in advance.
