I just bought a 2004 Daytona Blue 350z with the Touring Package.
I love the Bose system in there and well worth the price. I opted on the DVD Navigation System since i thought i could just add a LCD Screen and put a portable DVD/Playstation 2 in my Trunk.
I went to talk to a friend about installing an LCD screen and he told me that he could put a screen in but in order to get sound i would either have to use a FM Modulator or those Tape Deck Thingies. I don't wanna be ghetto and have wires or use the FM Modulator since that has bad quality.
I was wondering if the Bose system can be

1) wired to add an Aux port
2) if the Bose system has a Audio In to plug in my Media Device

I hope someone out there knows if there's a possible way to do this.
I don't wanna have to take out the bose 6 disc changer to install an Alpine or Kenwood DVD/LCD Deck for 2k+
Thanks
