Thanks very much, the iGO Primo works with the previous China Map provided by you. Can the iGO Primo display Chinese language? In my case, there are many blank squares, I suspect these should in fact be Chinese characters.
You need a suitable font to display Chinese characters.
1. Get a unicode true tpye font (TTF) with Traditional and/or Simplified Chinese, preferrably with normal and bold fonts. Search the net and download, or get it from the desktop PC's OS (eg Windows 7).
2. Rename them to tahoma.ttf and tahomabd.ttf (bd for bold font, if no bold font, make a copy of the normal font and rename it to tahomabd.ttf. It's OK but no bold fonts will be dispayed.)
3. Put these 2 ttf files in subfolder .../ui_android/fonts, at the same level as the ../content folder of iGO/Primo (eg, /storage/sdcard1/iGO/ui_android/fonts/tahoma.ttf). If no such subfolder exists, create one.
4. Reset the device and run.
