"The mobile phone as a personal navigation device makes tremendous sense,"observed Mark Donovan, senior analyst, comScore. "With the influx of devices,such as the iPhone with GPS, entering the market, Nokia's purchase of NAVTEQand the growing popularity of downloadable navigation applications, you don'tneed a map to see where this sector is going."

According to comScore, 73 percent of mobile subscribers accessing maps aredoing so via the browser in the U.S., and in Europe, 57 percent. Less than athird of Americans and Europeans are using a downloaded application, whichallows even feature phones, with less computing power and often smallerscreens, to better render graphic-rich maps and directions. Despite theubiquity of SMS usage in Europe, the penetration of consumers accessing mapsand directions via SMS is 24 percent; only one percentage point higher than itis in the United States.

The vast majority of mobile map users are seeking driving directions, evenin Europe, where public transportation and non-vehicular options are morepopular.
