Garmin HRM-Dual not working after less that 1 year. Should i change the battery? The spec states battery should last about 2-3 years. Any advice?
mine stopped working after 1 month.
I tried to replace battery, downgrade firmware on Fenix 6X to 9.00 (running beta 9.96, tried also 9.97).
After I take out battery and put it back, it finds the sensor, shows also "connected" initially, but the moment you start activity, it will not be found anymore, is in "searching"mode.
When I remove it from sensors and try to find it again, it will not be found anymore.
Anyone has/had the same?
