It apparently has Wi-Fi, but no word on an EDGE or cellular connections like the nuvi 1690 that is also due out around the same time. The 4.8 inch device also has a 3-megapixel camera which can be used for geotagging. Oh and it does all that navigation stuff too: lane assist, traffic receiver, text-to-speech directions.
The smaller 4.3-inch nuvi 1690 is reported to retail for $US499.99 (not including the connected services) and is now confirmed to use its EDGE connection for weather, flight statuses, gas prices, traffic and Google-powered searches. [Engadget]
