maps are difficult to make work with a blind orientated product as
they are so visual. the braille note gps which is really sendero
group gps took ages to get maps working. I think it is a bit like

in most cases a gps system has you as a red dot on a screen and it is
all visual. I think maps could be very difficult to get right.
