Hello there,
Good day. Thank you for your question.
FMC640 does have the option to use custom CAN under the Manual CAN IO (
https://wiki.teltonika-gps.com/view/FMC640_Manual_CAN_IO) but there are some details that we will require such as the CAN protocol syntax, vehicle type, and the available parameters. I will suggest to contact us via VIP Helpdesk or reach out to our 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 info@teltonika.lt
Thank you for your understanding.
Kind regards.
