-One method is to create a Decal, and then assign the Google Map image to it. Place the Decal on a horizontal plane/surface in the model. Note that you will need to scale the image carefully. Image quality may also depend on the map resolution.
-Decals only appear in Realistic and rendered views.

-Another method is to import the Revit model into Google Earth Pro.

- One more method: If you have Navisworks, it has a Google Earth add-in. Export your Revit model to .nwc, then bring into NW and use the Google Earth add-in.
