Garmin Express shows memory allocation and I've noted that ~4Gb is occupied by "My Music" and the rest 10,5Gb by "Other".
I believe it corresponds to advertised values but anyway, would be possible to remove something from "Other" to free up some memory for my music? I suspect that majority of space is filled by maps, and some of them I'll never use, so it would be safe to delete (at least temporary). Anyone knows how to do it?
