okay, I just read through docs. The following features are the only ones 
which seem to need NT:
Speed limits
multiple language support
postal code filtering
lane connections and junction view (note both not supported by 
Mapsource, mapsource cannot send this info to the GPS)

Not needed and possible without NT:
Date time modifiers (for restrictions) --- would be really nice if 
mkgmap supported this (it could give a push in OSM for such data)
Traffic events
RDS
extended turn restrictions
