That what I found out a while back. The mapsettings.cfg is incompatable between navcore versions (thanks TomTom!). The other way it can be done is to convert you favourites Mapsettings.cfg file to a POI using software called POIEDIT. But that containds a poi that is harder to find.
I also already posted instructions on the best way to migrate the old mapsettings.cfg into the new navcore mapsettings.cfg version.
