Sygic GPS Truck & Caravan Navigation is not launching, crashing, freezes

First of all, we're sorry that you experience this behaviour in the app. This interactive article covers all the basic troubleshooting steps that help resolve situations like this.

If you get a system message while the app runs that the app is not responding or stopped working, please report this using the "Report" option from the system error message.

Below is a quick interactive guide to help you troubleshoot this kind of issue. Respond "Yes" or "No" whilst performing these various steps to troubleshoot it properly:

1. Turn your device off and on again

This is to ensure that the crash is not caused by some random or minor system error.

2. Force close and empty cache

If the application stops responding or the problem persists, force close the application and clear the cache in the settings of your device> Applications> Sygic GPS Truck & Caravan Navigation.

3. Can you run the app?

If the application does not start, please skip this step. Go to Menu> Settings and select "Reset to defaults". Turn the app off and on again. This should help if there was a problem with the settings.

4. Is the application installed in internal memory or SD card?

If you have an application stored on an SD card, try to move it to the internal memory. If there is a problem only if Sygic GPS Truck & Caravan Navigation is installed on a particular SD card, it is likely that the SD card is faulty - in which case you have 2 options:

  1. Format the SD card (in this case, please back up all data to another storage medium as formatting all data from the SD Card is deleted)
  2. Replace the card. If it is an internal / hardware card error, it is possible that formatting will not resolve the error.

5. Please try reinstalling the app as the last option

As the very last resort, please consider reinstalling the app. Notice that this step will lead to the loss of your personal data in the app (favorites, saved routes, etc.) if you don't back it up. The location of your personal data is located beneath the reinstall guide.
