The AV system in the 2009 is the ugly duckling of the 370Z's. (Compact flash...really guys??) It was changed for 2010+ with more features (USB, BT audio streaming , Rear view camera support with dynamic track lines, DVD based upgrades, higher res screen with enhanced GPS, etc). If one has a 2009 370Z with navigation already, how much effort is it to swap the unit with a 2010+ navigation unit and screen? Being that car already has the nav wiring harnes, wouldn't it just be a matter of unplugging the 2009 unit and plugging in the 2010+ unit and swapping the higher res screen? I can't imagine that the wiring would be different but there is little info on the subject of swapping.

Has anyone tried or looked into this in detail? There was one post that seemed to die without a conclusion:
Swap 2009 navigation for 2011
