mapsettings.cfg
But may not work if TT have changed/modified the file's layout "Recent destinations" and a few other things are also stored in mapsettings.cfg
Best way is create your own POI file (I've called mine "Favourites") along with an icon (Favourites.bmp) and store them there and copy these two files to the new map's folder (Europe_955_4746?).
