My new Explore use Fahrenheit units in the (default) meteo widget. How can I change to Celsius? Thanks
You can't change temperature unit manualy on Edge Explore device.
It depends on language/country set in Garmin Connect Mobile app.
I had the same issue. To solve it I had to reset device to factory settings, reinstall Android Garmin Connect Mobile app, set up account, finally sync app with Edge Explore device.
