Hello Zakitek,
Good day. Thank you for your question.
FMX640 and Manual CAN could be used for this use case. However, FMB120 + CAN adapter or FMB140 will require development additionally. Please contact your Sales Manager if you require more information on firmware development. 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 info@teltonika.lt
Thank you for understanding.
Kind regards.
