You like using the GEOMAP command because aerials are displayed in AutoCAD with very little effort. You would be upset if you found that feature no longer works, right? Install the hotfix now and continue using BING Maps (and aerials) in AutoCAD.
Autodesk Knowledgebase article states it this way. “Microsoft® is ending support for version 7 of Bing® Maps on June 30th, 2017. This Hotfix will upgrade your version of Bing Maps to version 8 so that you can continue to use the Geolocation Online Map Data feature.”
