I've been on a couple of different boards trying to get igo8 to work on my 2din China unit in my VW. The software starts initially, then a screen comes up that says "navigation system" with a status bar underneath. After the status bar fills, it kicks back to the beginning and repeats.
The iGO8 version is 8.3.4.102680 and the folder structure on my SDcard is as follows:
content
custom
defaults
license
save
album.cache
branding.zip ...
