I have a Garmin nüvi 660 and I use the British bloke. However he has some quirks. He will say "Federated States of Micronesia" when it is referring to a Farm to Market road and when it sees a street name with ST at the end it says "Saint" instead of "Street."

The "Sheila" and the Ausie man are too hard for me to understand. Garmin's digital voice for that dialect was just poorly done.

Why can't we purchase celebrity voices like Jack Nicholson, Woody Allen, Marlena Dietrich or Paris Hilton? That's hot...
