Got the update installed yesterday (they also did the TSB for A-Pillar rattle, and replaced all 4 window moldings to reduce streaks). It is MUCH faster however I've already had 2 black screens. The difference this time is that after 30 seconds it reboot on it's own rather than me having to pull the fuse. But in less than 2 hours worth of driving having two black screen crashes is ridiculous in my opinion.
