Toys "R" Us via eBay offers the Garmin nüvi 50 5" Portable GPS Navigation System, model no. 010-00991-01, for $74.99 with free shipping. That's the lowest total price we could find by $18, although we saw it bundled with a dashmount for $6 less in December. The GPS system features a 5" 480x272 touchscreen LCD, voice navigation, lane assist, microSD card slot, USB connectivity, and more. It comes with preloaded maps for the lower 48 states plus Hawaii and Puerto Rico. Alternately you can choose full coverage of the U.S. and Canada. Deal ends April 24 at 2:03 pm ET.
