The Sena Momentum INC Pro has the ability to record on a 64GB microSD card but in order to get the video footage the card has to be removed and inserted into another device or SD card adapter. This should not be the case. The helmet uses USB for charging and updating the Sena 20S communicator portion of the helmet. Programming up a way to transfer the DCIM contents to a standard PC is expected to be available by default for the camera portion. Removing and reinserting the storage card over time exposes the card and slot to potential damage (breakage or water seal deterioration).
Please update the camera firmware to allow standard PC media communication directly when plugged via a USB cable.
