How to Fix Garmin GPS not Working?
Clocks with GPS connectivity can take a long time to latch with satellites. The amount of time it takes is determined by your location as well as other factors. Here are some suggestions for resolving all of these issues.
Check your connectivity
The first step is to ensure that your Garmin watch is connected to the internet, which is critical for using your GPS to locate any place. You may simply fix this problem by turning off GPS and restarting it.
Restart the watch to see if it helps. If your Garmin watch or tracker relies on your phone's GPS (known as Connected GPS), make sure Bluetooth is enabled on both your phone and your Garmin device, and grant Garmin Connect permission to access your phone's location data, setting it to Always or Allow all the time.
Hard reset your Garmin device

To begin, press and hold the Power button, which is located on the bottom right of the screen.
