I notice alot of people here were having problems with their Iphone or Ipod woring half the time or not working at all. I have done some testing here is what you should know. The Iphone 3g, 3gs and some Ipod is requring more battery power to operate correctly. If you are using the offical pioneer cables that has the audio,video, and usb in one cable you should be affected. For all you guys that are pulling your hair for it to work you need to seperate the audio/video from the usb cable...Just get a regular usb cable for your ipod or Iphone and connect it, your pioneer device will respond to it
