I have Zune HD and was wonder if I plug it the female 3.5mm plug that goes behind the receiver, it would work? I tried to plug my phone in and it didnt work. Do I have to change any settings? I know there is AV input behind the deck but this would be much more convenient.

Yes, read your manual.

LOL is that ur reply to all the posts? I did read the manual and couldn't find the info I am looking for or understand it if they did mention it in there.

Only on answers that can be found in the manual.
