Here’s another Korea-only personal navigation device that brings you the most bang for every buck you spend on it. Not only is it a video and audio player, it also has T-DMB and a Sirf III GPS antenna. It even has a built-in phone charger. Most interesting is the onboard alcohol sensor, a personal breathalyzer for drivers to avoid the one carried by the police. How much for this wonder gadget? Just $300.
