I recently got installed the new Pioneer AVH-P4450BT head unit here in Australia and the unit wont play Ipod videos. I have an Ipod Touch 4g and I've conected the Pioneer CD-IU200V Ipod video cable and all I get when I play a music video is a blank screen, no audio but the elapsed time is showing. All the mp3's play ok but I can't get the videos to show on the screen. I've searched some threads on here saying I need to go into the initial menu and then AUX1 and choose Ipod. I can't find this initial menu anywhere. I can go to system settings and find aux there and it just has on/off. I've even tried asking the Pioneer experts online and they just keep saying I have the wrong cable or your Ipod doesn't support this function. I've tried two different Pioneer Ipod video cables and I've also tried the 3rd and 4th generation Ipods and still no luck. Can anybody help me out here?????????
