NAV in Argentina

Hi,

There is no download (that I can see) for an Argentinian version of NAV. Can anyone confirm if that is the case and if so which version is usually used there?

Clearly the database must contain Spanish ML captions - is there perhaps a W1 database available with Spanish Language?

Also I understand that there are localistion requirements required for using NAV in Argentina, does anyone have any information about this?

Regards,

Joe
