I have the Nuvi 2557 and am extremely happy with it. The only downside is that it doesn't have lifetime maps. It has worked perfectly in Italy on my last trip. Yes it is a slightly older model but it works just fine and the pricing should be lower now than when it was first released. @:-)

I also have used the bluetooth feature on the Nuvi 2577 with my cell phone when using rental cars which provides me with hands free speakerphone capability.
