I’m not sure if the PG that the World Updates add to the sim, i.e. Tokyo, London etc, have the same coding structure as those already present in Bing Maps.
Their coverage is very limited too, see (London, Tokyo) vs (NYC, LA, Miami). London is only covered form east of LCY in the east to Piccadilly Circus in the west. Tokyo quite the same, only downtown. They are very scarce as especially compared to their extensive Google PG coverage.
