Video playback via and iPod should well...just work. Give us some more information.
Here are a few things:
- Do you have video content on your iPod that plays back fine on the iPod?
- Do you either have a PAC TR7 (bypass) or you are trying to play back while parked w/emergency brake engaged?
Do you get any playback at all? Are you getting audio and no video? A common problem with installation of the w900/910 is that the video cable (3.5mm) is hard to seat in the back of the head unit. You have to push to get it in all the way. If you don't seat it properly, you will get audio playback and no video.
