I also have the same problem.
I just want to set the default view on google map, not having to worry about which address was last entered in the last property. You also have a setting in your theme – Longitude and Latitude or the Google Map – this setting is not functioning, because it always shows New York.
The functionality we have now – correlated with the address of the property in list for taxonomy or advanced search is useful and you should keep that. The map show on these pages only the properties in the list. If you have a property in a certain part of the map, but the map starts with another area you set in admin – that would confuse a lot.
If you do not wish anything related to New York from demo – you must edit demo content as it follows:
– lat and long in theme options (2 places)
– lat and long in some page – custom header (we used that option too)
– lat and long for all demo properties – changed to something you wish.
