Step 1: Restart Your Polar Watch

A simple restart can fix temporary issues after a software update.

Follow these steps:

1. Turn off your Polar GPS watch.
2. Wait for 10–20 seconds.
3. Turn the watch back on.
4. Start a GPS activity outdoors.
5. Wait for satellite connection.

Restarting refreshes system processes after firmware changes.

Step 2: Sync Your Polar Watch With Polar Flow

After an update, your watch may need to synchronize new data.

Steps:

1. Open the Polar Flow app.
2. Turn on Bluetooth.
3. Connect your Polar watch.
4. Allow synchronization to complete.
5. Test GPS again.

A successful sync can update device information and GPS assistance data.

Step 3: Refresh GPS Assistance Data

GPS assistance data helps your Polar watch locate satellites faster.

To refresh:

1. Open the Polar Flow app.
2. Connect your watch.
3. Complete a full synchronization.
4. Keep Bluetooth enabled.
5. Wait until the sync finishes.

After refreshing GPS data, test the watch outdoors.

Step 4: Test GPS in an Open Outdoor Area

After an update, the first GPS connection may take longer.

For best results:

1. Go outdoors.
2. Move away from buildings.
3. Avoid trees and covered areas.
4. Keep the watch facing upward.
5. Wait until GPS locks.

Avoid testing GPS:

• Indoors
• Near tall structures
• Under bridges

Step 5: Update Polar Flow App

An outdated Polar Flow app can cause communication issues after a firmware update.

To update:

1. Open your phone’s app store.
2. Search for Polar Flow.
3. Install the latest version.
4. Restart the app.
5. Reconnect your watch.

The latest app version ensures better compatibility.

Step 6: Check GPS and Location Settings

Firmware updates can sometimes change settings.

Check:

• GPS recording settings
• Location permissions
• Sport profile settings
• Battery-saving options

Make sure:

• GPS tracking is enabled.

Step 7: Charge Your Polar Watch Fully

Low battery can affect GPS performance.

Try:

1. Charge your watch above 50%.
2. Restart the device.
3. Start a GPS activity.
4. Wait for satellite lock.

A stable battery level helps prevent tracking interruptions.

Step 8: Reinstall Polar Firmware Update

If the update was interrupted, reinstalling may resolve problems.

Steps:

1. Open Polar Flow.
2. Connect your watch.
3. Check for available updates.
4. Install the firmware again if available.
5. Restart your device.

Do not disconnect your watch during installation.

Step 9: Reset Polar Watch Settings

If GPS problems continue after an update, resetting may help.

Before resetting:

• Sync workout data.
• Save important settings.
• Confirm your data is backed up.

Reset steps:

1. Open watch settings.
2. Select reset options.
3. Confirm reset.
4. Pair the watch again with Polar Flow.

A reset can remove incorrect settings caused by software changes.

Step 10: Check for Hardware Issues

If GPS remains unavailable after troubleshooting, the issue may be hardware-related.
