German Addresses that contain umlauts (ä,ö,ü,ß etc.) are not found within the address search.
For example, it's impossible to navigate towns like: "Köln", "Hürth", "Hermülheim", "Brühl", etc.
Garmin, please make the address search smarter, so that umlauts and diacritics can be substituted with regular characters "a","o","u","s"... that can be found on the keyboard.
Thanks a lot!
