I was driving on the highway this AM, 110-120 kph, -11 Celcius, which isn't unsual at all in Canada. The central screen became totally unresponsive. The internet radio kept going and I could control it partially through the buttons on the wheel (play/pause/volume). Same thing for heating. The map kept updating. However, I couldn't access any function from the central screen. I tried stopping the car, and it didn't work. Needless to say it could have been a real problem had I needed to defrost my windows, etc. I contacted the service center. Have yet to hear from them. Anyone has experienced this? In my opinion it's a major failure... as defrosting windows is NOT optionnal in winter... and being unable to access the driving parameters menu is just as important.
