1:SDHC cab file -
The cab file is at the bottom of the first post. It should be labeled as "attachment".
2:Well so far I hav'nt discovered any ways as to splitting the 8gb card into two 4gb partitions. I havnt really looked into it so, I will look into it when I have some time.
3: As for navigation I use either "Microsofts Livesearch" or "Googlemaps".
Either one of the apps are great.
