So, it seems that Navigation.com is listing a wrong DVD code for 2011 update (Nissan 370z Roadster)
T1000-17499
Is Xanavi 7.0 2011 (same as Carminat 30.2), but the Xanavi System does not work with a HDD, it works with the DVD inserted in the unit!
This creates a lot of confusion, becouse all European Nissan dealers are clueless about HDD maps.
The only maps are from 2009-2010 and they come with the original HDD unit!
No one has seen/done an upgrade in
Europe...
