I am visiting Berlin and I would like to display the former location of the Berlin Wall in my OSMAnd app.
I have found the wall here: https://www.openstreetmap.org/relation/6651797
(or also here? https://fbinter.stadt-berlin.de/fb/wms/senstadt/k_mauer )
but I have no idea how to add this to OSMAnd? I have tried to find instructions but I am hopelessly confused.
Can any of you kind people help me out?
