The Garmin nüvi 1390LMT adds lifetime map updates to the nuvi 1390T (which already includes lifetime traffic). Introduced in 2009 (here is a list of more recent nuvi introductions), the 1390LMT also comes with lane assist, junction view and Bluetooth for hands-free cell phone use. All of the units in the 1200, 1300 and 1400 series come with customizable data fields and the ability to utilize the pedestrian and mass transit features on Garmin’s CityXplorer maps. They also have text-to-speech, so you’ll hear “drive one-half mile, then turn left on Main Street,” instead of just “drive one-half mile, then turn left.”
