I've seen that topic, but most of the files the downloaded package contains doesn't exist originally on the device. Also, CountryProfiles is in Route (settings?) folder. Shall I ignore that file or any other files that are not in Maps folder?
Shall I also delete all the other files in Map that were on the device? How is the device able to realize that the new map files are renamed to the new ones?
Also, TerrainEU as I've read it is not even supported by Nav 1210, shall I just leave that out to free up more space? (Only have 1,8Gb by default).
