Apropos updating: the accuracy for the GPS and marker on the map can be set to 5. It misses the actual location by maybe 50 m and lands in the park of the palais. (These are the GPS coordinates taken from Google Maps for the building itself: 51.05986047131598N, 13.737426909461458E)
Something is not right. This message is just to keep things from messing up down the road
