The device continuously loses the GPS signal every 3/5 minutes. I tried to select the different satellite options (GPS, GPS + Glonass and GPS + Galileo) but continues to lose the signal for a few seconds (2-3 "). The Garmin connect synchronization works but does not solve the problem. (With PC windows 10 and Anroid phone)
The problem has sometimes been there but it has been much worse since the upgrade to FW10.
