At the beginning, when I first installed the software, I set Settings-System-Location format to hddd.dddddd, which is my favourite format. I was expect the software will fully support this format. However, I found it only works for display (e.g. Point Information in map view), but doesn't work for input mode (e.g. Where to?-Coordinates still hdddmm.mmm' format). Later on, I was trying to change some POI location using coordinates, cause street number based mapping isn't so accurate. I got weird keyboard poped up, but can not change anything. I realize that it maybe works switching back to default hdddmm.mmm' format. When I switch back default format, then it works. Seems like it is a Garmin software bug.
