Just a few of quick observations/questions in configuring Navit on the N800...

autozoom_active="1" seems to work, although autozoom_secs="n" does not seem to do anything. I was expecting to be able to temporarily zoom out and have the display zoom back to the autozoom level in force after n seconds, but instead the display zooms back instantly.

Secondly, I cannot see a way to turn spoken instructions on or off via screen buttons. I have tried
<osd type="button" x="632" y="516" command="speech.active" src="mybigmouth.png" />
and even
<osd type="button" x="632" y="516" command="toogle_announcer" src="mybigmouth.png" />

Thirdly, the route selection on the N800 with an OSM map seems quirky or even amusing at times. I am guessing this is all down to the quality of the OSM map and cannot be tweaked inside Navit? Examples include instructions to turn right when the displayed map shows the correct route is to go straight on following a main road over a set of traffic lights, and the selection of silly small roads rather than prioritising major roads and motorways.

Finally, are other graphics drivers available on the N800? sdl / qt_painter? I am guessing not.
