On the original question about snow, I get that too, on occasion. It seems to do the snow ( or white noise as it is called ) intermittantly for a few seconds and then goes away for no apparent reason. I have the iPhone 5 connected via an HDMI cable only. The factory 30 pin cable is plugged into the back of the head unit, but it is not connected to anything. By the way, I had this problem with my iPhone 4 and with the 30 pin cable connected too, so the phone or connection doesn't seem to matter. My HDMI adapter for the iPhone 5 was purchased through the Apple Store, so that isn't the problem either. And, I'm on firmware 8.30. Anybody know of a fix yet?
