I am located mid Michigan. I'm curious as to whether others have noticed whether (GPS + Glonass) OR (GPS + Galileo) works better and this area?
Personally, I'm using (GPS + Galileo) in my tracking seems to at her match the maps that I get when using my iPhone GPS with the RunKeeper or MapMyRun apps.
I have been reluctant to change back and forth as the correlation between the garment GPS and the iPhone GPS tends to vary enough to make comparisons difficult.
