Amazon’s got a one-day deal on the 4.3-inch Garmin nuvi 855 GPS at $160, down from $190. You can still get it by Christmas with one- or two-day shipping, too.

The device features turn-by-turn voice directions, lane guidance, direct transfer of Google and Mapquest maps, MP3 playback, and expansion via microSD. For a GPS system that normally costs almost $200, it’s a tad disappointing that there’s no built-in traffic receiver or Bluetooth but you can at least add the traffic part after the fact, if need be.
