Instead of placing the map screen for your navigation in the center console where you have to take your eyes off the road, VDO Dayton's MS5700 places it right up into the rear view mirror, where you're "supposed" to be looking anyway when you're driving.

The unit has all of Europe's maps stored on a dual-layer DVD, plus has 9 languages, 21 voices, 2D/3D maps, and a 4" display on your RVM. – Jason Chen
