Garmin's successor the cellular-enabled nuvi 1690 PND, the unimaginatively named Garmin nuvi 1695, has been spotted clearing the FCC. Official specifications are unknown, but the nuvi 1695 is expected to have a touchscreen UI, Bluetooth and GSM connectivity; the latter will likely be used for mobile access to Google Local search information.
Otherwise it's likely to have a 4.3-inch display, like the 1690, and use the Bluetooth for hands-free calling. Garmin has also been playing around with a database of average road speeds based on historical data, which they call trafficTrends, so it seems likely that will make an appearance too.
In the US, the nuvi 1690 uses AT&T's EDGE network for its connection; it seems unlikely Garmin would want to step up to 3G in the 1695 given the power requirements. No word on when the nuvi 1695 PND might see an official release, but judging by the fact that Garmin's request for temporary confidentiality lifts on August 1st 2010 it can't be too far off.
