The hits just keep on coming out of the recent Korea Electronics Show, with the folks at AVING providing a belated glimpse of yet another PMP/GPS/DMB combo unit, this one from Korean manufacturer Ezex. Dubbed the NAVZEN, this device bucks the recent trend of 7-inch inch displays, opting instead for a leaner 4-inch number, though it adds some picture-in-picture functionality if you prefer your DMB TV even smaller. Complete details are a bit sketchy, with Windows CE 4.2 confirmed as the OS and SiRF Star III as the GPS chipset but not much else. It will, however, adjust the volume based on how fast you're driving, which could well make this the most dangerous PMP on earth.
