Hi Peter, David, Re: the Nokia as an open source-based accessible talking GPS, in fact the open source GPS software already available for the N800 will use Flite (which has been ported to the N800) to give speech output. The main problem, as was already noted in this thread, is getting map data designed for a pedestrian. The public databases for this info (e.g. Google) are designed for automobiles. But once that piece is addressed, you should have everything needed to make the N800/N810 a talking GPS for accessibility use.
