Zoho CRM

New user here, after many months of evaluating different systems. I'm having problems with the Google maps integration- great feature but it doesn't work for me right now- is this is UK only issue? Surely it's trivial to pass at least the postcode as the query to Google as that's more or less enough for us. When I click on the map button it ignores the postcode altogether, so Google gets very confused and just shows me a picture of the whole of the US!
