From:ABC News. Here's a snip:

"I'm sure we all have a GPS horror story to tell. Those nifty devices sometimes takes one on longer routes than necessary, lead one down roads that no longer exist or always seems to find the worst traffic.

A Swedish couple vacationing in Italy may win the GPS booby prize. The BBC reports that the couple wanted to visit Capri, off Italy's west coast near Naples. When they arrived at their destination they asked around for directions to the island's famed Blue Grotto all ready to take in some sun and the stunning sights of rugged cliffs plunging into the sparkling blue Mediterranean.

Instead they were informed that they were 400 miles off course in the industrial town of Carpi in northern Italy. Pilot error... or how two transposed letters can change everything."
