Why won't the panoramic image open? Clicking it doesn't respond, and it also doesn't switch to the camera when I put it in reverse gear. What's the reason?

I've upgraded my 2009 Scirocco with the 187b head unit, but the reverse camera doesn't switch the screen when reversing, although the radar works fine. Interestingly, the reverse camera works normally when the car is off, but not when the engine is running. I've already replaced the head unit and the reverse camera, but the issue persists. Any experts out there who can help?

Has anyone encountered a situation where the 2017 Smart car doesn't respond when put in reverse gear, and the engine warning light is on?
