** FAQ **

Q: The watch face shows "Please start an activity" or "no geolocation". What do I do?
A: In order for the watchface to get the GPS location info you need to start and complete an activity with GPS (e.g. Run or Bike). After that the watch face should show the weather within the next 30 minutes.

** How to enable current weather **

1) Get free OpenWeatherMap account (https://home.openweathermap.org/users/sign_up)
2) Copy OpenWeatherMap API key (from https://home.openweathermap.org/api_keys)
3) Go to watch face settings (http://forums.garmin.com/showthread.php?332843-How-to-App-Settings): check "Display Weather Info" checkbox and paste API key in "OpenWeatherMap API Key" textbox
4) Let the watch get the current GPS coordinates by starting an activity with GPS
5) Wait for the watch face to retrieve the weather info (this takes a couple of minutes)

The weather info is updated every 30 minutes (if there is connectivity). If the weather info is more than 60 minutes old, it is shown in gray.

** How to enable dual time **

In the watch face's settings, change the "Top Display" setting from "Heart Rate" to "Dual Time". Then pick the time zone in the field below ("Dual Time Zone"). If you want a time zone that is not a full hour, e.g. UTC+05:45, select time zone "UTC+5", and then the minute offset "45" in the field below ("Dual Time Zone Minute Offset").

** Set 12- or 24-hour time **
