From this website you can download Gfix by Xavier Cany.
For users using the Google Chrome web browser, you will be able to see Google Maps on the Activity 'Details' page.
This functions on Mac and XP computers.
A great first step - hopefully similar solutions will be found for the 'Player', 'Explore' and 'Dashboard' pages in GC.
