Enable Location in Settings. Here are three different ways to Add GPS.
1 Tap Memorials/Search Memorials to find the memorial. Long tap on the memorial, tap 'Add GPS.' The coordinates for the location of the grave will upload to the memorial.
2 Tap Cemeteries/Search Cemeteries or the map to find the cemetery where you are located. Tap on the list of memorials in that cemetery. Memorials that have a map pin icon to the left need GPS added. Search for the last name and long tap the specific memorial in the list. While standing at the gravesite tap 'Add GPS.' The coordinates for the location of the grave will add to the memorial.
3 Photograph the headstone or grave and upload it to the memorial through Add Photo. GPS coordinates automatically upload with the grave photo when your Location services are enabled.
