You're not allowed to text and drive, but you can play around on your Nintendo DS. Not to find treasures as Zelda, but to check to see if you're going in the right direction to the banquet you're headed to. A new program called Kuruma de DS turns your handheld gaming system into a remote control for car navigation systems. Via bluetooth technology, you can see optional maps on the DS and input where you want to go. The main Smart Navi system costs about $2,586 and the Kuruma de DS chip costs $92. Kinda pricey, if you ask us.
