I had this situation occur again this morning. I still have 2.0 B3 loaded, so I'm not sure if it's due to that, or just a general issue. The one thing that seems to be similar to the last two times it happened is that the player had been in the car overnight, with rather cold weather. The vital signs in hijack v76 showed a reading of -6c.

I have seen the player boot up dim, then correct it's self when the player program starts, and remember Hugos comment on it from the meet. But this seems to be the opposite problem, and could potentially be resolved by resetting the display brightness a few moments after the player program starts, since any time I either turn on my headlights, or go into the dimmer settings, the problem is fixed.
