I followed that Jiri's howto. Nokia maps says "Welcome to improved Nokia maps" out loud, but program cannot run any further. The progress bar keeps on moving left-right-left even for hours if I wait.
I I close it [X], it says "bye bye".

What could be wrong?

Edit:
Got it back to work (without voice navigation) by replacing old index.html and pfw-directory from the backup.

Edit2:
The jiri's index.html work, I can hear some instruction now and the map otherwise works, but not with the pfw-directory taken from jiri's page but with some old one I installed last autumn.

Because there is no diff program available for N900 (?), I cannot easily see what are the differences.
