Groupon offers the factory-refurbished Garmin nüvi 1490LMT 5" Widescreen Portable GPS Navigation System, model no. 010-00810-02, for $79.99 with free shipping. That's $6 under last week's mention of this refurb and the lowest total price we've seen for this model. (It's $15 under the best price we could find for a refurb unit today.) Features include a 5" 480x272 touchscreen LCD, free lifetime traffic and map updates, lane assistance, eco-friendly route planning, preloaded maps of the United States and Canada, microSD card slot, USB and Bluetooth connectivity. A 1-year Garmin warranty applies, the same as for a new unit.
