From the MCU version screenshot you uploaded, it does look quite old. That can sometimes cause issues with things like steering wheel controls or power management. However, it may not be directly related to the reverse camera issue.
I’d recommend trying the latest update (you can download it from the OTA update thread) and see if it helps.
At the same time, I’m not fully sure what kind of problem you’re running into (no reverse image showing, or no reverse trigger at all?). If you can share a bit more detail, I’ll do my best to help you out here.
