This was kind of strange, but last night during the normal 50 mile commute home the MFD and Instrument Panel cut off, and then came back on a second or so later. The MFD was on the climate or info page but after the reboot was on the 'Click Accept' screen of the Nav. We had been driving between 60 and 70, with the Front Defrost on, and just before it happened had hit the horn (Crazy NY Driver swerving all over the road coming into out lane...). To me it sounds like the old '05 issue has been fixed by making the computer reboot instead of lock up, anyone else have a better idea?
You probably hit the map button when you hit the horn. I've done it myself, but I usually turn off the Auto AC.
