Hello Matisoft,
Good day. Thank you for your question.
You can update the SW of the CAN adapter (in this case it's ALLCAN300 + FMC130) via FOTA WEB (free) or using a Bootloader (needs purchasing). Please use this link on how it can be updated using FOTA WEB -

If you do not have a FOTA WEB account with us, then kindly contact your Sales Manager/Distributor. If you don't have any contacts with our Sales managers, please contact them on our official website

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 in advance.
Kind regards.
