You can find directions on mobile phones, but I guess this makes it smoother. For it to work in countries like ours we need more better mapping.
. . . Google announced a free navigation service for mobile phones on Wednesday that will offer turn-by-turn directions, live traffic updates and the ability to recognize voice commands. The service will initially be available on only one phone, the new Motorola Droid, but will be expanded to more phones soon.
In a briefing on Tuesday in advance of its announcement, Google said that the service might be supported by advertisements in the future. That would make driving directions the latest form of information to shift from being a paid service to one that is ad-supported.
“This is consistent with a certain pattern of Google, where they are able to build volume and usage of a product and then subsidize it with advertising,” said Greg Sterling, principal of Sterling Market Intelligent, a research firm. The losers, he said, were companies like TomTom and Garmin, along with the cellphone carriers, which offer navigation services by subscription.
