navigational systems

My favorite piece of technology is easily the navigational system for my car. My dad bought it last Christmas as a present for my mom. She had no need for it but realized within five minutes that it was the perfect solution to my problem. Having NO sense of direction, the navigational system gives me comfort when I am going somewhere for the first time. It also accurately estimates the arrival time. Although I try not to be too dependant on it, it has made driving so much less stressful for me.
