Probably the most convenient feature of the nüvi, after navigation itself, is the Arrival Time indicator, conveniently located in the bottom-left corner of the Map screen (Figure 4.5). It gives you an amazingly accurate estimate of the time when you'll arrive at your destination and updates itself in real time based on your current speed.

The first time I used this feature was when my wife called to ask me when I'd be home for dinner. "At 6:12," I told her. She made fun of me for the precise response, but I pulled into the drive at exactly 6:12—to her amazement (and my own!). Generally, the closer you are to your destination, the more accurate this feature is, but on this particular day, I was more than an hour away from home.
The arrival-time feature is your friend, and you'll come to appreciate it very quickly.
