Hey guys, I was doing some research on the nav system in the SI's, aparently 04 and 05 are different than 06+. My old Rx8 was hit head on and totaled, and I'm looking at a replacement 2006, but this one has nav.

Now, I know I can go on Denso's website, and they offer a 2011 update disc for the 2006 rx8 with nav, as you can see here: Deprecated Browser Error

My question is, does anyone know if any current model year's of maybe the 3,6, etc, or the Series II's might have a current 2015 disc that would read with the nav system? The searching i've done yielded almost entirely questions about the 04-05 navs, which are different.
