Feature Request individual codes, or USB apply?

[pharnos]

Hi all,

Is it possible to use individual Feature Request codes for NBT EVO version K?

I want to:

• VO code fix
  
• region unlock
  
• full fsc
  

Currently the headunit is NBT EVO version K but I'll update this in the future to P,Q,R,S+ etc and want to make sure I have the individual Feature Installer codes if I need to perform VO code fix, region unlock, full fsc again.

I notice most websites offer VO code fix etc for NBT EVO version K as a file to run from USB drive. Would obtaining a Feature Installer code be better for the future when I have NBT EVO version P,Q,R,S+ ?


Thanks!
Steve.
