EasyCar U7, 7-inch GPs for $100? Where do I buy?

Our friends from Aving have spotted a 7-inch GPS called Easycar U7 which reportedly costs only $100. It has being presented as a low-end navigation system, but it seems to have a very decent resolution (looks like 680×480, see photo gallery) and has many of the multimedia functions including digital TV , video and music playback, so it’s a really cheap portable media player (PMP) as well. The question is: where do we get them (outside of Korea)?
