I had a Dacia Stepway before the MG, on the Navi you could enter coordinates, just type them in. I had lots of POI's mainly for things such as fossil locations, edible mushrooms, ruins and locations where there were other things of interest which I extracted as coordinates to transfer to the MG.
I can't understand how 'Hear' can release a navigation system that doesn't allow you to enter coordinates.
Will have to use Mapy cz on my phone to visit locations then store them on the MG as favourites.
Good job Mapy works on Android Auto.
