More than a third of drivers with factory-installed navigation systems use personal navigation devices anyway. That's according to a study released this week by J.D. Power and Associates.
The 2010 U.S. Navigation Usage and Satisfaction Study, released Friday, found that 36 percent of those with installed navigation systems use PNDs, while 28 percent "prefer receiving directions" from their PNDs. The study also found that 24 percent of factory-installed navigation owners use a smartphone for directions and that 28 percent prefer the smartphone.
"Portable navigation devices and smartphone navigation both offer a less expensive and more convenient alternative to a factory-installed navigation system," Mike Marshall, director of automotive emerging technologies at J.D. Power and Associates, said as part of the announcement.
