iPod classic won't play on Sony dock
I have a 160GB iPod classic that I purchased about 1.5 years ago. I have been using it on the SONY ICF-CS15iP docking station ever since. A few weeks ago I played the iPod on a different Logitech speaker system and now my iPod will no longer play music through my SONY dock. When I put it on the Sony dock it will charge, but will not play through the speakers nor respond to the ipod controls located on the dock. The sony dock will still play music from my iPhone 4S but not the ipod classic. Help please! Thank you!
