i recently updated my iphone to ios4 but now my z110 wont allow me to control my ipod from the navi screen itself, only from my iphone. has anybody had thos problem/ any idea how to fix it?! when i switch to the navi controls it would first freeze. i'd hit the play/pause button and it would pause. so id hit it again and it still wouldnt play. i don't know what to do or if its the ipod cable itself. i dont think so bc i can still play music as long as i control it from my iphone. help/suggestions/ ideas??????
