I was playing with the left TFT menu. In the menu "settings" and "car settings" / park sensors "stop and" i changed the input. Now the parksensors are visible on the screen when i go under 10 km/h. So far so good. But now i cannot activate the MENU button anymore when I'm standstill !!!!! Just the parksensor aid is visible in the TFT. Then i push the menu to try to change settings again and nothing happens in the TFT (still park sensor window). When I'm driving the TFT changes and i can use the menu button, but then i only have the "speed limit input" option. I page 107 this is described. My guess is my dealer dont have a clue. I´m stucked.
