Nissan GPS Navigation DVD

[LDRydr]

I'm looking to upgrade the DVD for the GPS Nav system in my '06 Nissan Altima but I'm too cheap frugal to get the just-released version for $99. Has somebody here upgraded theirs and wants to part with an earlier one? The new version is v6.8 so I'd be looking for something like v6.7 or v6.6.

Here's list of Nissan vehicles it would need to come from:

Altima 2005 - 2006

Armada 2004 - 2005

Maxima 2004 - 2005

Murano 2003 - 2005

Pathfinder 2005

Quest 2004 - 2005

Titan 2004 - 2005

X Trail 2005 - 2006

Z Coupe 2003 - 2005

Z Roadster 2004 - 2005
