The Garmin nuvi 205 is a good entry-level unit that does a decent job of calculating routes quickly. There is some level of user customization allowed, but in general not as much as a comparable Tom-Tom unit would offer. It has been said that Tom-Tom is the PC of the GPS world while Garmin is the Apple of the GPS world. While it isn’t rated for water or dust resistance, it has been splashed and roosted and it’s still kicking. Current model equivalent would be a nuvi 30.
