Hello community, especially in autumn and winter I have an unpleasant problem with the smearing of the windows with my 607 and would like to have some practical tips from you. Forward: I changed the indoor air filter (used a model with activated charcoal). The air conditioning is always running during the ride (even if it shuts off automatically from any threshold) and the windows have been treated with an anti-fog spray from Sonax. In addition, I have in the Inn At the beginning of the winter I also changed the outside temperature sensor. Now the correct values are displayed again. The fogging was even more extensive before these actions – nevertheless it still disturbs. The 607 is often moved for long distances during the weekend. During the week it is often outdoors, but also the accommodation in an underground garage has not changed the behavior. As far as I can see, it is in the indoor and outdoor areas. In the 407 I read that there is a temperature and humidity sensor, which is supposed to prevent the fogging of the windows – is this also possible with my 607? If necessary, this sensor is also defective… Thank you Sebastian
