Download and install EdgeAllinOne as single datafield following these steps on your device:
Activity profile - Data Screens - Add New - Custom Data - Choose single layout
In the ConnectIQ collection select EdgeAllinOne1.

After installing this datafield on your device, various settings can be made. This is best done with Garmin Express (PC) or Garmin "Connect IQ Store" (mobile, recommended!). Instructions for this can be found here:
https://support.garmin.com/en-US/?faq=TMj0wxIdjh382mBFh5rG46

Both the metric and the US-American system of measurement are supported.

The following languages are currently supported:
-English, German, French, Spanish, Italian, Polish

To use the power section, a power meter must be connected to the device and the values of the individual power zones must be stored in the settings.
For the heartrate graphs the heartrate zones are taken from your profile. It is therefore necessary that the zones are set in your device!

For the display of wind bearing and wind force, as well as the outdoor temperature, the data of a nearby weather station must be available via Garmin Connect Mobile. The app must therefore be loaded on the phone (but it can work in the background) and has to be connected to your device.
