Good day. Thank you for your question.
The configurator you are using doesn't support the current firmware of the device (likely that the firmware may be outdated). I will suggest using a different configurator if you have the older configurator version or you can obtain it from your Sales Manager/Distributor. If you don't have any contacts with our Sales managers, please contact them on our official website https://teltonika-gps.com/
and click on the "Contact Us" button. When you will click, please fill the form and submit it.
Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with the description of your situation to firstname.lastname@example.org
Thank you for your understanding.
