Good day. Thank you for your question.
Please find the COM driver in this link https://teltonika-gps.com/product/fmb920/#downloads. Go to Driver Utility > select FMB PC Drivers and download > Run > check the device on Configurator. You may install it under the C drive which will be auto-selected or you can manually choose it. Once the installation is successful, you will see your device appearing on the Configurator. On the Device Manager Mobile, you will see it as device model_last 4 digits of the IMEI as default.
If you are still having issues connecting the device, kindly reach out to us via VIP Helpdesk or contact our Sales Manager. 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 email@example.com
Thank you for your understanding.
