I've found, that pre-facelift 2012-2013 Supersports and Flying-Spur equipped with new head unit (RNS-810) and different instrument cluster.

Is anybody know, is it possible to retrofit this improvements to 2008 GT?

 

I believe the last year of the 06-12 Flying Spur in 2012 had the new head unit. Since the new Continental was already out that probably made some wiring changes. Not sure if you can just swap those units into pre-2012 Continentals or Flying Spurs.
