Last 3 years, my EDGE 1000 works perfectly and I had always turned-on GPS+GLONASS by default. Last 3 days I´m facing first time with "not acquiring satellites" issue. I reset it on factory settings but it doesn´t helps.
If I use only GPS, then it finds satellite and works normally. When I choose GPS+GLONASS, it finds satellites every 10 - 15 mins for 4-5 sec. and most of time is in searching mode, without connection.
Bluetooth & WiFi is OFF by default.
It is updated on latest version v15.20.
