Now that I've made a preliminary foray into the mysterious universe of the intelligent telecommunications device, I find myself also becoming curious about these vehicle GPS units. My wife has one (a Tom Tom), which I have used twice. It twice failed to take me to the intended destination without some swearing and other, non-verbal forms of persuasion. That one is about two years old now. At the time, my daughter claimed that Tom Tom was the highest rated automobile GPS on the market.
So, fast forward to today. For an entry-level or lower mid-level unit, what's best? Tom Tom, Garmin, or Magellan? What's good and what's bad about each?
