Actually, this is a better home for it.
I have managed to plan my route using autoroute, export the resulting map(s) (complete with route drawn in green) and using the locate button in autoroute you can get the gps co-ordinates for he top right and bottom left of the map before you export it.
The maps can then be converted to png and loaded onto the zaurus.
import the maps into qpegps adding in the co-ordinates for the two corners, and you then you just follow the green line.
It cannot be automated, as getting the co-ordinates is a manualy process.
Like I mentioned, its only good for pre-planned routes.
I have also managed to get qpegps plotting the free uk speed camera database onto the maps as well. This is ongoing and not finished yet, in fact I haven\'t touched it since I got my 760, but I wil resurect this at some point.
