According to the USA Today, more and more rental cars are being equipped with GPS navigation and satellite radios. Only five years ago did CD players become a standard and now we have stuff being beamed down from space. Many people I know seem to love the Hertz NeverLost navigation system and has added them in 50,000 cars. I'd love to see how it compares to my recently purchased TomTom Go 300. Some people even carry their own navigation systems while they travel. As the size and cost of these devices shrink, we'll see that more often.
