Does any one know if there is a fuse box type junction that allows for extra 12 volt accessories to be hooked up on the model S If you wanted to permanently mount a device it would not always have to be plugged in to the cigarette lighter. Would be nice if some open ports could be turned on and off through the 17 inch display. This type of hook up would be useful for other 12 volt devices. I also heard that there was going to be a 110volt outlet somewhere as well. Anyone heard other wise about either?
