iTouch issues after installing Adaptatunes app - HELP!

I downloaded Adapatunes and now my Clarion M475 is having problems flipping through menus, in particular the playlists. I have my iTouch (Gen3 model) connected through a Cnet cable.

I understand the Adapatunes won't work through the Cnet cable but thought if I wasn't worried about volume / speed control I could still use it through the Cnet cable.

Sometimes it starts out OK but then it will go through the playlist very very slow then I get a bunch of dashes and then it just gets lost. And it quits to where I can't get it to do anything.

I uninstalled the Adaptatunes and I am still having the trouble.

Any ideas on how to fix this??

Thanks
