If in Europe, the US or the rest of the world, we can easily find our way in a city, with the help of street names or house numbers, doing the same in Japan is much more complicated, for the simple reason that there are no street names or house numbers, but a complex system of districts and blocks and house (i.e. 3rd district, 9th block, 4th house). By the way, Akihabara News is located at 6-17-10 (we will soon have 135sqm offices, Hip Hip Hip Hurray). So you can easily understand that without a GPS in your car, you risk getting quickly insane figuring out directions. The latest Clarion GPS, the DrivTrax P5, is an autonomous SiRF GPS with 2GB of expandable internal memory (with its SD port, for audio and video), and a 4.3” display. It measures 132×90.5x22mm, weights 198g and has 4.5 hours of autonomy. It runs Windows CE 5.0.
