One of the problems facing makers of GPS units is how to make maps that drivers can use while paying attention to the road rather than the screen.
One answer was audible directions, but as it happens, telling people to turn left at Third Avenue isn't much better; people lose sight of the road when they strain to read street signs.
Garmin's Nuvi, demonstrated at the Consumer Electronics Show in Las Vegas, changes that with an improvement that has been in the works for years: audible directions that rely on visible landmarks, mimicking the directions many people might give. Instead of saying "Turn left at Third Street," Garmin's new system will say "Turn left at the stop sign," or "Turn left after the Starbucks." The feature, Garmin Real Directions, will be on six models ranging in price from $200 to $380.
