Hi Julius.
We haven’t used a Google Map for some time now. The online map uses ESRI map layers.
If you are using the Mac version of LINKPlanner, then the online map is not available. However, if you are using the Windows version of LINKPlanner then it should appear automatically. If you have problems on Windows then checkout this suggestion from syadom - Link Planner google maps crash, resolution?
Thanks,
Andy
