I'm probably on of the few people in the world who doesn't have or uses a cell phone so I've never considered it. My wife and I have a track phone in our car but haven't used it in years -- the number probably doesn't work anymore. I Just have a maps under my seat, or google directions and print out a map if I need to go somewhere.
Met-in stands for '(Hel)Met-in. As in the helmet goes in here.
