The nuvi 1690 we first mentioned couple of weeks ago, and later again with more details was just made official with a press release and has already hit Amazon ($500).
nuvi 1690 is a GPS navigation system from Garmin that includes a wireless module that lets you use the new nüLink! service. nuLink service can connect to Google local search, traffic, weather, fuel prices, movie listings, flight status, and white page telephone listings. There’s also “Ciao!”, Garmin’s location-based social networking system. (Who thinks Ciao is going to take off?)
There’s of course a service charge for all the connectivity (EDGE only) – but thank god it is free for the first two years – and more than likely you’ll be ditching your device anyways 
Some specs of nuvi 1690 include 4.3-inch WQVGA touchscreen display, bluetooth, and the 4 hours worth of Li-Ion battery.
As far as software features you’ve got the ecoRoute, text-to-speech, Pedestrian Navigation, maps for the United States, Canada, and Puerto Rico, and Multi-Point Routing.
