Hema Nav - 'Hema Nav' won't start

Troubleshooting Steps for How to Get Back into 'Hema Nav'

If your Hema Nav app crashes on startup—showing a black screen before returning to the home screen— below are steps for two possible methods to fix the issue.

 


 

Method 1: 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.

 


 

Method 2: Delete vstore.bin

In early versions of Hema Nav there was an issue which would sometimes occur when the unit shut down during track recording. If a unit is having this issue, it can be resolved by following the steps below to delete the file that is causing problems.

  1. From the home screen, press Settings.



  2. Tab the third tab (Device), then scroll down and press the button labelled "Delete vstore.bin".

 

You should now be able to open Hema Nav without issue.
