Problem using the google map address

Hi Guys,

I am not able to add the location of the business owner in the listing even if he is there in the map. I am trying the exact address and the map address both alternatively but the result is something else. How can we put the address in the map field so that I get the correct location displayed in the map. Or, If it is not possible what is the alternative. I find Mappress very fit for this job. Can I use it in place of the default google map in the theme.
I am sick of this and this is very frustrating.

Please Help.

Regards,
