I have the w505 hooked up with the PTR7. I can watch DVD's while driving. My problem is with 120gb ipod classic. I can play music and I get the album art. When I try to play a video from the ipod the screen goes black, but I can hear the audio. I have TV out on and set to NTSC. I don't know what settings could be left that I didn't try? I have the usb Y cable with the video extension. Anyone know what this could be?
