I had it switched on today when I picked up one of our regular fares a lady who happens to be blind. She heard the female voice from the sat-nav and asked me who else was there. I explained what it was and she was fascinated, so I programmed in her destination and let her listen as it guided us there.” How big is it” she asked so I handed it to her and she was amazed to feel how small it was.” Do you think I could use one” she asked”, it would be great for me to find my way round “I explained that she would not be able to enter stuff into it without sight. She was very disappointed, but as I said to her in the next few years you may able to get voice activated versions. She said this would be a boon to her and other people in a similar situation.
