Changes

The [[Garmin Epix]] has slightly better accuracy with WAAS than without it, and GLONASS didn't degrade the accuracy the way it does with other devices. My belief is that enabling WAAS effectively disables GLONASS, as WAAS is GPS specific (and only available in North America.) There is EGNOS Ground Segment is the equivalent of WAAS for GLONASS/GPS/Galileo in Europe.)
