More Sony news from CES. Trying to grab some goodness from companies like TomTom and Garmin, Sony is showing what it calls the Nav-U portable navigation system. It's small and with the easy-to-use bracket, it won't take me hours to figure out how to position it in my car. Kudos, Sony. Another nice addition is a 3.5-inch touchscreen, and there's a two-way speaker system that makes sure your voice prompts don't get lost on the way. The guts of the thing include a 12-channel GPS receiver with proprietary RF technology and a built-in antenna that lets you use the receiver the minute you pull it out of the box, as well as 1GB of flash memory preloaded with maps of the continental U.S. (and 1.6 million "points of interest," like that giant ball of string in Wisconsin you've been dying to see). Also comes with a DVD-ROM with full maps of Alaska, Canada, Hawaii and Puerto Rico. You can update any of the maps by connecting the Nav-U to a PC with the included USB port. I kinda dig what they call the day and night modes, which changes the brightness of the screen with a sensor that measures ambient light. This should run you about $700.
