In Oct. '06 we rented a car in London. Drove south and west to Cornwall then north to Swansea Wales- up the coast to Snowdonia and crossed back over into England then down to the Cotswolds. The GPS was a god-send. It got us through back roads as well as cities. We enjoyed the proper Victorian English lady that spoke to us over our two week trip. She was most polite. "At your easiest convenience please make a u-turn."
