So I had the pleasure of rebooting the display today while driving due to Slacker being stuck and not doing anything. I had to turn right before, and my turn signal was going when I rebooted. I normally rely on the sound to tell me it is still engaged, but since the display took like 30 seconds to reinitialize the sound was off, and I only noticed I still had turn signal going about a minute later when I saw the arrow blink on the dash display. Kind of an aha moment for me since I didn't realize the sound had to do with the main display. While it was rebooting the GPS was obviously stuck where it was, but good to know speed indicators and such still work.
