play video

Hey guys!! First post on here im pretty good with cars when it comes to mechanics but not so great with the audio part i just installed my new pioneer avh-280bt in my 2005 vw passat 1.8 turbo it has dvd player cd player bluetooth aux snd usb my friend was telling me that i can play music videos...

My Equipment AVH-P4000 DVD Seagate 250gb HD ZUNE 16HD I have my portable hard drive connected via USB to my head unit and it works fine....for audio. Question #1 - Is video playback allowed through USB? I know that you can connect a zune into a HU's AV connections. Question #2 - Is there...
