When I hit the image on the touchscreen (it's not a button! ) for the front Defogger, it does two things: It puts the heat on HI and the Fan Speed on 8 (max)...I figured out how to turn the fan speed down (from the right-hand click-wheel), but as soon as I try to lower the temperature, it shuts of the Defogger...Anyone else having this problem? Anyone figured out a work-around? I'm on version 4.1, FYI...Thanks
