POI Question

Not sure how POIs are distributed, whether they are included with the maps or not, but can you get updates for them?

I have recently installed a map of Greece and there only appears to be a number of POIs; nothing on tourist attractions or banks for example despite being enabled in the settings.

Should they be there or am I missing an update? Or it is just they don't exist for this map?

Thanks

POIs are included in the map. Additional POIs are available through TT Home.
