When updating the firmware, please format the USB flash drive to fat mode and then move the update package to the flash drive and extract it. Then using a Type C cable, plug the USB into the Type C harness and dock it to the Type C port on the dashboard. Finally power off the car and apply the brakes and the data will update automatically. There is no need to disconnect the power and don't unplug the USB flash drive during the data update process. It will restart automatically when the data is generated. After reboot, don't pull out the USB flash drive, because for the time being, the data of the APP is generated. We also need to continue to generate data for the protocol. After the data is updated to 356, we can unplug the USB flash drive. After unplugging the USB flash drive, the whole upgrade process is finished, just wait for reboot. You can set the adjustment parameters by sliding the scroll wheel !I purchased one of these and installed it today. Where do I get the firmware updates?
