A GPS that speaks in street names
Staring at your GPS unit's pretty maps while driving is a bad idea, but the spoken directions ("Turn left in 600 feet") often aren't clear enough to steer by.

With the optional traffic receiver incorporating Clear Channel Broadcasting's real-time traffic data into your maps, it'll even talk you around any upcoming jams. $1,185
