Aguri sat nav won’t update apps, software, or maps – “Cannot access server. Please try again later” error message

If your Aguri sat nav displays “Cannot access server. Please try again later” when trying to update apps, software, or maps, the problem may be caused by the time setting on your device. Google services require your sat nav to have the correct time in order to sync and connect to the update server.

How to fix it:

  1. Go to the Main Menu on your Aguri sat nav.

  2. Tap Settings.

  3. Scroll down to find the Time/Date setting.

  4. Change the setting so it uses Network instead of GPS.

  5. Check that the time shown matches the current local time.

  6. Try the update again – it should now work as normal.
