Hello David,
Thank you for your inquiry.
FM6300 is compatible with our dashcam MVC300 with a special firmware version. But MVC300 is end-of-life product which means that we didn't make or sell them. But if you will need it, you can find dashcam via resellers.
Please let us know if we can help you with any questions.
Sorry of any inconvenience.
Best regards,
Teltonika Support
