I'm looking at getting a 2006 TL with Navi any day now. I want to add iPod, Sirius and video/audio from a portable media player. After looking around, I think I've seen a couple ways to do all this.

1) Audio: The P.I.E. aux switcher (module + cable)
Video: PNVI Dual Video Input or Soundgate VIDHOND2
2) Alpine vehicle hub

With #1 I am concerned about being able to switch to correct video and audio source. For instance, audio from the PMP and the video from the PMP. Then if I am listening to Sirius or iPod will I have the ability to view the navigation?

With #2 I am not sure I can do video in.

Has anyone done all this? Which is my best bet for all I want to do?
