Good day. Thank you for your question.
If you are referring to the configuration application, then we have the PC-based application called the Teltonika Configurator which can be downloaded from here - https://wiki.teltonika-gps.com/view/Teltonika_Configurator_versions
. However, please take note that these are the latest Configurators and if you are using outdated firmware, then it would not be supported.
Therefore, you will need to use the Updater which you can obtain from your Sales Manager/Distributor. If you are referring to the phone application then we do have the BTAPP but it is used as a Driver Notification, for more info please refer here - https://teltonika-gps.com/product/btapp-mobile-application/
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.
