Engadget Compares Smartphone Navigation
Engadget does a head-to-head comparison of three GPS smartphone navigation systems: Google Navigation, Ovi Maps, and VZ Navigator.
So which is the nav for you? There’s zero platform overlap here, so if you already have a smartphone in your pocket and you’re happy with it that will be the one and only deciding factor. Android? Google Nav. Nokia devices? Ovi Maps. WinMo or BlackBerry on Verizon? VZ Nav. But, if you’re ready to jump on a new contract, get yourself a new toy, and want the one with the best navigation which is it? Well, it depends.
Note that a consideration of iPhone navigation options have been set aside for another time. (No surprise there: too many of them.)
