Connected PNDs have it rough. Ever since Dash folded, the future has been murky at best for any GPS company hoping to rope consumers in by promising real-time information on the face of their navigator. Garmin, however, is hoping to get folks hooked by avoiding that awful monthly fee for the first two years on its nüvi 1690, and it's using AT&T's network in order to do so. Today, the carrier proudly announced that it would be the one providing service to the device, giving users within range of an AT&T tower access to Google Local search, updated fuel prices, white page listings and Garmin's own Ciao! social networking system. What's interesting, however, is the high-profile nature of the partnership. We'd hate to speak too soon, but would we be nuts to think a whole cadre of AT&T connected GPS units were on tap for, say, CES 2010? Guess only time -- and sales data from the 1690 -- will tell.
