Turn by turn navigation on Nokia N900 with voice guidance using community extension of OVI maps N900 users have been neglected in this respect by the company, but fortunately the community developed an improved version of OVI maps for N900 itself, particularly thanks to Blaizzen and CormacB. There was some confusion in the discussion thread, since the two versions posted were not compatible. For some reason I do not know, the HTML5 version does not work on my phone, so I will describe how to install the one by Blaizzen using the python server. There is no distribution package yet at the time of writing this note. I have made some modifications, particularly to run the python server forever, and let it listen only at the localhost interface, and switching off the "onto street_name" part of voice guidance, since it did not work properly with Czech street names anyway. (Probably it might work if I would switch globally the phone localization to czech and change the language in the python server, too, but I do not like to do this.) To install and run it do the following: 0. assuming your phone locale has been set to english_us in the setup menu, otherwise change appropriately 1. Login to N900 as root 1.1 apt-get install espeakgui espeak libespeak espeak-data wget unzip 1.2 (optionally) espeak 'hello world' to check that it works 2. cd /usr/share/nokia-maps/html 3. mv index.html index.html.nokia; gzip index.html.nokia 4. wget http://www.pittnerovi.com/jiri/hobby...00/maps.tar.gz 5. tar zvxf maps.tar.gz; rm maps.tar.gz 6. cd /home/user/MyDocs; mkdir navigation_sounds; cd navigation_sounds; wget http://static.s2g.gate5.de/maploader...english_us.zip 6.1 unzip english_us.zip (do not rename to .wav) 6.2 cd /usr/share/nokia-maps/html ; ln -s /home/user/MyDocs/navigation_sounds/english_us . 6.3 change SOUNDPATH in speak_02.py if using different language directory 7. nohup ./speak_02.py >/dev/null & 7.1 (optionally) wget -O /dev/null http://localhost:9999/hello ; wget -O /dev/null http://localhost:9999/:g5ann_001 (to check that it works with both sampled and synthetized speach) It tried to install and then did not want to open .... load. 8. start OVI maps from the GUI.
