If you’ve ever used a GPS device for directions, you might already be acquainted with Karen Jacobsen.

As the voice of “Australian-English Karen”in Garmin GPS products, she calmly instructs harried drivers to turn left, go 1.8 miles or “recalculate”their trips every day.

Jacobsen recently spoke with the Chronicle’s Kristin Finan about her sense of direction, being yelled at by strangers and how her virtual gig with Garmin has helped her achieve celebrity status in real life.
