Summary: Easy to read and follow. Like the way it recalculates when a change in course is made. Like the display, especially the picture of certain exits. Easy to program and to find locations using the search capability.
Summary: Performs beautifully. Rapid startup and location of satellites and rapid, trouble-free map updating. So far, the traffic alerts have been accurate and timely. Some of the spoken driving instructions can severely mangle the pronunciation of the locations, but that's more humorous than a problem. I consider the 2457LMT good value for the price.
Summary: Bought this item because of the live traffic update....only to find out that live traffic updates are really limited. As a result we got stuck in a four hour traffic jam because we hadn't been warned about an accident that had happened 10 hours earlier but was still blocking the freeway. The item also gave us instructions to our house that would have taken us at least 30 minutes out of our way if we had been a visitor and not known how to get home. Very disappointed.
Summary: I got this GPS to update my older Garmin, I have used it in France & the USA, it works well. Very fast to start up and calculate maps. The display is crisp and clear and the traffic feature is amazing.
Garmin nuvi 2457LMT Couldn't Have Made It More Easy
2 October 2013
Summary: It was time to upgrade to a new GPS. Since I had a Garmin before (same one for the past 8 years) and was pleased with it I decided to stick with another Garmin. Paying for the updates was the main reason for purchasing another one with Life Maps and Traffic and I'm sorry I didn't do it earlier. I did as much research on the different types of units as I felt I needed. I finally settled on the 2457 LMT.
Summary: This is my very first GPS and I love it. My only issue with it is that when it's connected to my computer, there is no indication that it is even charging or when it is finished charging. But charging it in the car is great.
