Is there a config.xml along with the sound files? You could also get the indonesian voice files from http://symbian.clanteam.com/indexmaps.htm or http://www.hpsblog.com/2009/07/direc...0-without.html

Step by step instructions for Indonesian:

I am assuming the indonesian voice files are zipped in a file called indonesian.zip from the linked site and all files are saved to MyDocs. Otherwise you might need need to change some paths.

• Download index.html.gz from here http://talk.maemo.org/attachment.php...3&d=1295624977
• Copy your voice files to your N900
• Open X terminal and become root
• Run
  
  Code:

  cd /usr/share/nokia-maps/html
  mv index.html index.html.backup
  cp /home/user/MyDocs/index.html.gz .
  gunzip index.html.gz
  cp /home/user/MyDocs/indonesian.zip .
  unzip indonesian.zip
  rm indonesian.zip
  cd indonesian/ind-bahasa_male
  for f in *; do mv $f $f.wav; done

• You now should have config.xml in /usr/share/nokia-maps/html/indonesian and a bunch of wav files in /usr/share/nokia-maps/html/indonesian/ind-bahasa_male
• Startup maps and create a route. It should automatically use the selected "id-ID" locale to pick the right sound folder.

Edit: the attached updated index.html will show an error message if it can't load the voice config. It also is possible to change the language used by renaming the folders or changing the _codeToFolder mapping in index.html

I also don't know if it is possible/how to change the language for maps so that I can test this myself
