Well, that was interesting..... I normally keep my multi-information display on either compass/speed limit or on audio information. Yesterday, I switched from compass to audio and was greeted by a totally blank display. Switching through all of the other displays (using the < and > arrows on the steering wheel) gave the expected displays - only the audio was completely blank. Turning the audio system on and off made no difference. Power cycling the entire car brought it back. I'm a software engineer by trade - looks like sloppy code and nothing watching for crashed tasks, just like the run-away acceleration ECU problems a while back. Sigh...
