Turn it down again and it becomes louder and louder, etc. Can't even turn the music off because it is locked. This creates a really dangerous driving condition when you constantly have to adjust the volume while driving.
Same thing has happened to me twice. Most recently 2 days ago. I commute 45 minutes, and it happened 10 minutes into my drive. The only way around it is to stop, turn off the engine, and wait for the screen to go blank. Since that forces a reboot, I can get my Nav/radio/everything back.
I am hoping the upgrade fixes that little fun.
