Step 1: Open the Files App

• From the home screen, open "All Apps."

• Select "Files."

Step 2: Locate Internal Storage

  2. Tap the three horizontal lines in the top-left corner.
  3. Select "HX-2."

Step 3: Locate and Delete the vstore.bin File

• Once in internal storage, find and open "Android."
  

• Open the "Data" folder.
• Locate and open "com.hema.navigation."

• Scroll down and find "vstore.bin."

• Press and hold on "vstore.bin" until it is highlighted.

• Tap the Bin icon in the top right corner.
• A pop-up will appear confirming the deletion—press "OK."

Step 4: Return to the home screen

Option 2: Re-install Hema Nav licence

If the previous steps did not resolve the issue, another thing you can try is reinstalling the Hema Nav licence.

1. Ensure the unit is connected to Wi-Fi, then open the Update Manager
2. Long press Hema Nav - Licence^[1], and press Download^[2] on the menu that appears
   
3. Wait a few seconds to allow the file to download.

   Note: There will likely be no visual indication that a download has taken place.

4. Long press Hema Nav - Licence^[3] again, and press Open downloaded file^[4] on the menu that appears.
   

   Note: If this option does not appear, you may need to tap the date/time in the top left of the screen, press Clear Downloads, then try again from step 1

   
5. You should then see a popup like the image below indicating the process was successful.
   

   Important: Launch Hema Nav once with Wi-Fi connected to allow the online activation of your licence. This will only be required once after updating or re-installing the licence file.
