I just took delivery of my new 2004 Black Rx330 with Nav, Rear Entertainment and have a question regarding how to hook up my IPOD or other devise utilizing the Aux inputs in the back and have it play through all of speakers.

After putting a dvd in the rear ent. system I have been able to make the ipod work on the rear ent. headphones, but not through the speakers, the dvd plays through the speakers not my IPOD. Does anyone have any suggestions or directions?

This is my first post, although I have been a member for a while. I appreciate all the info and thank in advance for any help.
