Although I think I know a little about how the AVIC works, I confess to complete ignorance about the licensing of map. A view confirmed by my current inability to get 2011Q4 Navteq or Tomtom (TeleAtlas) maps to work on my UK F900BT despite having scanned the forum for help.
Mind you not knowing what I am looking for doesn’t help.
As I understand it, Pioneer provides a licence to run the Pioneer provided maps in a particular area.
However to run other maps you need:
a generic IGO worldwide licence
a Pioneer licence specific to the maps that you want to us
