Trouble with quick radius maps, or where do you put the api-key

I have been reading a lot on this and I have not found the answer. I have successfully followed the instructions at the link below to add a “map” to the detail view of a record.

In essence it tell how to create a field data type Iframe to show a map for the contact in a new field by placing the following statement as the default value.{primary_address_street}, {primary_address_city}, {primary_address_postalcode}, {primary_address_country}

You put your api-key in it and it works.

The problem is when I attempt to use the “Quick Radius Map” I get the following errors.

“Google Maps API error: MissingKeyMapError” js:34:315
“Google Maps API warning: NoApiKeys” util.js:210:33
“Google Maps API warning: SensorNotRequired” util.js:210:33
Use of getPreventDefault() is deprecated. Use defaultPrevented instead. index.php

Using SuitCRM 7.7.8 on Lamp server (ubuntu) fresh install.

So what am I missing? I have been able to find no documentation as to where else to put the api-key other than as stated above.
