Yes. To easily and quickly perform an in-dashcam format, with the DR600/650 powered on, simply hold down the Wi-Fi button for approximately 10 seconds. A beep will be heard from the BlackVue, and then a message "Formatting the SD Card...". After a few moments, another message will be heard indicating the BlackVue is rebooting. Once the unit reboots, it will resume normal operations. It's still a good idea to perform a full format of the memory card periodically (click here for the full-format procedure), especially if you begin having performance issues with the dashcam..
