Nokia plans to add navigation to half of the phones it sells within a few years to find new revenue streams amid decreasing handset prices, a senior official at the world’s top cellphone maker said.

Michael Halbherr, the head of Nokia’s location-based activities, told Reuters he remains comfortable with Nokia’s year-old goal for seeing up to 50 percent of its phones equipped with global positioning system (GPS) chips in 2010 to 2012.

“We are planning to ship 35 million GPS units this year,” Halbherr said, adding “and many more location-enabled phones that use cell-towers to orient themselves on the map”.

“You will see few ‘E’ or ‘N’ Series phones without GPS,” he said.
