I could go on, listing even more useful or cool features, including free traffic updates for one year ($10 annually afterwards). When it comes to unique features, this is a terrific GPS navigation app.

Now, the caveat: In a couple of instances during several weeks of intermittent testing, the mapping data was outdated or just plain wrong. For example, on one occasion CoPilot Live told me to turn onto Army St. But the street’s name was changed to Cesar Chavez St. 18 years ago.

CoPilot also instructed me to turn right onto 22nd Street when traveling north on Diamond Street. But 22nd Street turns into a steep staircase at this point before resuming after a block. If I’d turned right as CoPilot Live instructed, I’d have landed in a private driveway.

While these aren’t catastrophic errors, they’re enough to embed an element of doubt in my mind about CoPilot Live’s directions. In all fairness, however, every GPS navigation app I’ve ever used—and I’ve tested more than half a dozen over time—has steered me wrong at one point or another. It’s just a shame that CoPilot Live, which gets so many things right, doesn’t always deliver in the mapping department.
