With this display in the display, the system is annoying after about 10 to 20 minutes drive and falls off. But, only on the day. At night there is no propeller. I cleaned the sensor and environment behind the cover. Elktric contact interrupting is probably not possible, because at night everything is ok. Oh yes, there is something else. The cover in front of the sensor has been renewed (GP0). Old was scratched. That guaranteed me all this is fitting, because of mm-wave permeability. What is going on? Is there a software that needs to be reloaded? I am grateful for every tip. I have no desire to use the system only at night. F.G. Manu
