Just a comment. I am in Tokyo right now so can have some tries on the software. Yesterday when I was on the bus from Narita to Shinagawa, the software did very well showing the route the bus was going, even at the turn or intersection, but tonight when I was walking on the street in Shibuya, the routes were all messed up, which seems like there were too much interference or something went wrong with the map data... I do not have a screen capture software with me to record these strange phenomenons though.
車子走在大馬路上時,衛星訊號都會比較好接收。如果你是走在人行道上,那已經算是馬路的邊緣了,訊號就可能會被旁邊的建築物影響到。
我想你說的沒錯. 在澀谷大街上捧著 PDA 外加一個 "大" CF GPS 已經夠窘了, 螢幕上顯示的 GPS 路徑還歪七扭八, 甚至能 "穿牆".... 本想自我炫耀一下, 卻僅讓我的日本朋友笑翻了天...

當然, 在高速公路上就比較正常... 只是偶爾過橋時也會 "下水" 繞一下再回到大路上...
