At the CeBIT trade show in March, Mio announced its new line of "Moov" navigation devices. The previous generation of Mio products, all branded under the name DigiWalker, were powered by the company's version of Nav N Go's iGO software. (We've reviewed a number of these devices, including the fully-loaded DigiWalker C720t, the moderately priced wide-screen C520 and the entry-level 3.5-inch screen C220.) The new Moov devices are powered by in-house software developed using technology from Navman, a GPS company Mio acquired last year. As a result, the interface on Mio devices has changed considerably. Although I like some of the differences, especially the Moov's new text-to-speech conversion, multi-segment routing, and multiple language support, the company has taken a step backward in the way it presents points of interest (POI) information. And on our tests, the Moov 200 was sluggish with POI searches.
