My car has a heated windscreen element which I believe is the issue hence I have tried placing the sat nav at the edge of the screen to try and avoid the element but still no signal. The sdat nav is updated and I have checked the serial number to ensure it is not a pre roll over Apr 2019 model. Please can anyone help me?
