I can count the number of times I have opened the faceplate on my HU on one hand. Once or twice tops, one was set the splash screen and ecodrive settings and again to hack into the bios to retreive my password that I thought I forgot (but apparently just typo'd 3x).
Oh and for the record, those things are easy as hell to break into if you know what to look for. I retreived my "encrypted" password in about 5 minutes
