Ok Guys they are now available, Nissan has just introduced an iPod Interface, what this does is if you have the 6 CD system, there is a port on the back of the radio, you hook this interface cable to that port, and put the cable into the glove box, you hook your iPOd to this cable, and WAM! you have complete control from your head unit, scan songs, see the lcd display, and it also charges while hooked to this cable.
This is an awesome kit, and it is a Genuine Nissan Parts, so you get the factory 12 month/ unlimited mileage warranty.

Go to my site, and go to the interior section of the Xterra, Pathfinder or Frontier.
