I have had this device for 3 months and for first 2 months, it showed the accurate temperature - since then it has got stuck on 20.4 degrees and never changes. How can this be resolved?
Same problem. I have 27 degrees.
Have you tried resetting the device? Hold the power button for 10 seconds until it blacks out and restart it. This won't erase your data.
Yes I tried your suggestion and it worked! Many thanks.
The temperature on Garmin is coming from mobile phone. Connect phone via Bluetooth and will update the weather.
