If I have on the bike, the Edge 820.
The grade on the forest trails is shown as 0 no matter if I set the GPS to GPS+Galileo or GPS only or GPS+Glonass.
In the same time, the eTrex 35 touch show the correct grade.
Both devices on the bike at the same time.
I even loaded the track to navigate thinking that if the *.gpx is loaded the elevation profile is easy to read by the device.
Could someone fix that issue because it makes the device useless for MTB where the grade is very important.
When I enter under 2-3 trees no grade is shown on the Edge 820 but on other devices is shown.
I have the Edge 820 on my bike for 2-3 competitions this year, but this issue drive me crazy because is the most needed feature among the HR on the screen.
Crazy.
