pioneer ipod help Options

[pepsiman]

Hello, I have the cable hooking my ipod nano to my pioneer headunit through the cd changer port (I think that what it is), and it worked great for a while. Now it just says ready like it always did but it doesnt get any farther, like it wont load up the songs or any playlists or anything. Ipod says its connected, and the headunit responds when i plug and unplug the ipod. I returned the ipod back to its original settings already. Idk what else to try, the manual doesnt help much.
