I recently had a hands-on demo on the reliability of Sat Nav. I was on foot, carrying an A-Z , in Wimbledon Street, Leicester, when a car complete with Sat Nav drew up next to me and asked where Morledge Street was. It was the next street along, but the Sat Nav had it right here at Wimbledon Street. A case of Sat-Nav Nil, Map-Nav One. Also the hardware needed to update Map-Nav, a biro, is cheaper and easier to obtain than that needed to update Sat-Nav, and most Map-Nav users already come with the necessary software, unlike Sat-Nav users who have to buy their programme.

I hope it might be of interest to some on the list. cheers martin
