Could you please help us confirm the following:
• What were you doing when this issue occurred?
• Does the device perform its normal self-check during startup?
• Are both the wheel base and steering wheel not being detected?
If neither device is detected, please try manually flashing the firmware and repeat the process a few times to see if the issue can be resolved.
