TOKYO: 25 Oct. 2019 — Satisfaction with the aftermarket navigation systems has increased in all factors, according to the J.D. Power 2019 Japan Navigation Systems Customer Satisfaction Index StudySM—Aftermarket, released today. 

Now in its 12th year, the study measures customer satisfaction with aftermarket in-dash vehicle navigation systems. Six factors comprised of multiple attributes are examined (listed in order of importance): navigation function (27%); audio and video function (19%); display screen (18%); design and texture (17%); ease of use (14%); and other functions, apps and services (5%). Satisfaction is calculated on a 1,000-point scale. 

“Overall customer satisfaction with aftermarket navigation systems has increased since last year. We specifically see an increase in satisfaction in the display screen because of an enlarged screen and improved visibility, which were originally and creatively developed by manufacturers,” said Atsushi Kawahashi, Senior Director of the Automotive Division at J.D. Power. “In addition, satisfaction has also increased in the user-friendliness of Apple CarPlay, the improvement of the user interface, including voice recognition, and the accuracy of vehicle location.”

Following are some key findings of the 2019 study:

  • Overall satisfaction increases by 18 points: Overall aftermarket in-dash navigation system satisfaction averages 623 (on a 1,000-point scale) in 2019, up 18 points from a year ago.
