Hi at everyone.
I have a Garmin 935 APAC with firmware version 13.40.0.0 and since it was updated to this version when riding with the "bike" application, at approximately 12-14 km (20 minutes), the device stops showing speed and distance (neither shows nor saves them). It does not seem to be a problem of the GPS signal, it has happened to me in four consecutive occasions and always when that time has been running and only with the "bike" application (with the "run" application it does not happen).
I have tried to change GPS, GPS + Glonass and GPS + Galileo, but it also happens so I think that it is not a problem of the satellite signal.
At the end of the ride, although the distance shown isn't correct (the 12-14 kms indicated), in Garmin Connect does show on the map the all route correctly (???). The speed is not saved either. I use it with a Garmin GSC 10 sensor that does display and store the cadence correctly and it hasn't shown any problems with the Garmin 935. The heart rate is shown and data stored. I also deleted all previous rides in case it was a storage problem on the device.
Has anyone had a similar problem? Can a previous firmware downgrade be performed?
Thanks
