Most American drivers say they've been burned more than once by their GPS navigation systems, according to a new survey commissioned by Michelin.

In the online survey of 2,200 drivers, 63 percent reported being taken off track an average of 4.4 times since starting to use global positioning systems. Younger adults between 18 and 34 said they'd been given wrong directions 6.3 times. An unfortunate 7 percent of motorists were misdirected more than 10 times.

The fallibility of GPS systems is "something that we all kind of think is true," said Tony Fouladpour, a Michelin North America spokesman, "but this actually quantifies it."

The errors could result from out-of-date map data, said Phil Magney, an analyst at research firm IHS Automotive.

"That has been an industry problem for some time," Magney said. "You could buy a new car today and the GPS data could easily be a year old. That's how long it takes to get through the supply chain."

The survey uncovered demographic differences among the 30 percent of U.S. adults who use the high-tech in-car systems. Men (35 percent) are more likely than women (26) to use GPS.

About half of drivers still keep road maps and atlases in their cars.
