No, it is not a Pro-only feature or issue, it should be available and working in SketchUp Pro and Make.
With that phrase you left the most important fact unknown (what is happening when you click “grab”). Can you describe a bit more, does SketchUp leave the dialog open just as you didn’t click “grab”, or does it complete the action and close the dialog but without that the map appears in the model?
What operating system (Windows #/OS X #.#) with what browser version (Internet Explorer #/Safari #) do you use?
I am having the same problem with Pro 2015. When I click on ‘Grab’ the window just hangs. Doesn’t seem to be processing. I notice that on an earlier post about this problem someone mentioned that Flash might be the culprit?
First: Why can’t you import Google Map into SketchUp Model? What happend / what did you observe to come to that conclusion? The description of a problem is the way to its solution.
