Diamara

I picked up my x254 in march this Year and after an OTA (3e of april) my rearview camera flips in and out every time i brake (28kmh) and accelerate (38kmh). The sound that is procedures by the camerasystem is very irritating (30-40 times in 1 ride). I can calibrate the system by driving in a straight line below 38kmh (works also for the x253). Problem is that it won’t hold the calibration after shutting down the car. Anybody else with similar problems?
