62s won't read .img files

[JackS]

Followed other post and changed upload to gps to newname with .img endings to load additional maps. gps wont read any changed files. Even tried changing back to gmapsupp.img and would not read it either. Is this a defective unit or am I just doing something wrong. Not having much luck with 62s.

Are the files in the Garmin folder at the root of either a memory card or internal memory? They must be there to be recognized.
