It might be possible. Maps is actually coded part in javascript and part using a microB plugin (as far as I can tell). The javascript side of things is in /usr/share/nokia-maps/html/index.html The second part is the microB plugin which is located in /usr/lib/browser/plugins/npatlas.so (at least I think so... I'm a little unsure of this). Since the plugin is closed source, we can't change that, but the javascript file can be changed. In terms of changes, I've thought about maybe finding the distance between the new turn images/signal that came with PR1.2 and the current position. And if its within a certain distance, maybe play a sound or something. The issue is though if we go off the track, it won't recalculate the route, which at the moment is more annoying than no voice
