Learn how to troubleshoot GPS signal issues that may cause inaccurate positioning, delayed navigation instructions, or incorrect speed information.
If your device or the Sygic Truck & Caravan Navigation app cannot obtain a stable GPS signal, navigation may not work correctly. GPS signal issues are usually caused by environmental conditions, device settings, corrupted GPS assistance data, or hardware-related problems.
If your device or the app cannot obtain a stable GPS signal, you may experience:
- Incorrect speed display
- Irregular position updates
- Delayed or missing voice instructions
- Navigation arrow not following your actual location
Before troubleshooting
Before proceeding, make sure that:
- Location Services are enabled on your device.
- Your device has a clear view of the sky. GPS reception may be affected by buildings, tunnels, dense forests, covered parking areas, or other physical obstacles.
- You are moving. GPS accuracy improves once the device can determine your direction of travel.
Basic troubleshooting
Many GPS-related issues can be resolved by completing the basic troubleshooting steps which include:
- Force closing the app
- Restarting your device
- Clearing the app cache (Android)
- Resetting the app to default settings
- Reinstalling the app
For detailed instructions, refer to the article about Basic troubleshooting steps in Sygic Truck & Caravan Navigation.
Reset A-GPS data (Android only)
If the issue persists after completing the basic troubleshooting steps, try resetting A-GPS data.
A-GPS (Assisted GPS) data helps your device determine its position more quickly. If this data becomes outdated or corrupted, GPS signal acquisition may be slower than expected.
You can reset and download fresh A-GPS data using a third-party application such as GPS Status & Toolbox:
Open the GPS Status & Toolbox app.
Select Reset A-GPS data.
Select Download A-GPS data.
After the update is complete, restart Sygic Truck & Caravan Navigation and test GPS reception again.
Consider a possible hardware malfunction
If GPS is not working correctly in other navigation or location-based applications as well, the problem may be related to your device's GPS hardware.
In this case, we recommend contacting your device manufacturer or retailer for further assistance.
FAQ (Frequently Asked Questions)
Why does my position jump or lag on the map?
This usually indicates a weak or unstable GPS signal caused by poor reception, environmental obstacles, or device-related GPS issues.
Is resetting A-GPS data safe?
Yes. Resetting and downloading new A-GPS data is a standard troubleshooting step that can help improve GPS acquisition performance on Android devices.
What should I do if GPS does not work in any app?
If all location-based applications experience the same problem, the issue is likely related to the device itself rather than Sygic. Contact your device manufacturer for further diagnostics.
How do I know if the app has GPS signal?
Check the navigation arrow in Sygic Truck & Caravan Navigation:
- Orange arrow = GPS signal acquired
- Gray arrow = GPS position not detected yet
If the navigation arrow remains gray, wait a few moments in an open area with a clear view of the sky. If the issue persists, continue with the troubleshooting steps.
