Let Garmin Guidance 2.0 lead the way
The nüvi 2455LMT incorporates Garmin Guidance 2.0, a feature set that offers convenience for everyday travel. You can find and select businesses right on the map screen without having to go through time-wasting menus. Speed limit displays with visual warnings on major roads help keep you in check. You'll see photoReal™ junction views that provide easy-to-read and realistic representations of complicated interchanges, including signs. You'll also find a photo viewer, "Where Am I?" emergency aid, audiobook player, trip planner, and other legacy Garmin features.

Garmin 3D Traffic
The nüvi 2455LMT features free lifetime traffic updates using Garmin's 3D Traffic service, which is more expansive and timely than ever. 3D Traffic incorporates data from active devices on the road, historical traffic patterns, and other factors like construction, concerts, and sporting events to give you a comprehensive look at congestion in most metropolitan areas. Best of all, you won't have to pay a penny more for this service over the life of your nüvi.

Stay on course
The 4.3" nüvi 2455LMT's color touchscreen display lets you view the action in either portrait or landscape orientation. You get maps of the entire U.S., plus most of Canada, Mexico, and several Caribbean islands, along with over 8 million points of interest for stopping points for everything from an ATM to emergency services. You can add custom points of interest to give your journeys a personal touch.

You'll have Lane Assist to guide you through interchanges, plus text-to-speech voice prompts that announce actual street names at turns. In select instances, the screen will split automatically to give you a photoReal view of the junction so you'll have a clear picture of the next turn. When you're on the highway, the navigator can give you a quick listing of stopping points nearest the exit ramp to save you from searching.

Crutchfield Customer Review (What's this?)

This is my 4th Garmin over the last 10+ yrs. I like many of the map view enhancements, speed limit is shown and you do not need to enter the city to search.



Usually excellent...occasional quirks

BL from Boston, MA on 7/16/2012

Crutchfield Customer Review (What's this?)

It's usually very reliable, but I've found updating problematic...slow and not always accurate. And...even after updating the maps just before I left on a long trip, I had problems with the unit telling me to make illegal turns in some places. Oddly, it also told me to make complicated turns at places where U-turns were both allowable and possible, so I often took the short route to do that. Split roads (roads that have access roads alongside for local traffic, for instance) often confuse it. In Philadelphia, for instance, it kept telling me to switch from the access to the main side (5 times over a few miles). I had to do it, because I didn't know where I ultimately would have to leave the road. It turned out all of it had been unnecessary, since the two sides combine before I had to leave the road. I also like the feature my other GPS unit has; that one shows me the next TWO turns, so I know roughly where I want to end up after I make a turn. This unit doesn't supply that, which I find a detriment.

Pros: compact, can slip in a back pocket when you leave the vehicle, lifetime updates, usually very accurate

Cons: updates are time consuming, setup requires both computer and car so I had to take a laptop into the car for the first few steps of setup, the small size means you sometimes can't see the turn in detail until the last moment, occasional glitches so watch signs and don't follow the unit without checking it (it will sometimes tell you to make illegal turns)

CarlF from Monroe Township, NJ on 2/29/2012

I chose this model based on positive reviews. However, within the first 30 days of use the screen froze and I was unable to shut it off. I returned it and received a prompt replacement. After 1 week of using the replacement, the same thing happened and I will be returning this one as well. I will not try a third one.

Crutchfield Customer Review (What's this?)

Don't hesitate to buy it if your in the market... I think you'll really like it. Be sure to get the model with the lifetime map option.

Pros: Easy to use - I bought this for my newly licensed 16 year old daughter. Easy to update with the lifetime update-able maps. Accurate and much better than my old gps unit. I will likely buy another!

Cons: no negatives so far!

2455LMT Good product

MHAB from New brunswick, NJ on 11/3/2011

Crutchfield Customer Review (What's this?)

Great usable product. I love the fact that the map and traffic is for life time of the product. although the traffic warning hasn't worked yet and i have already been stuck in two traffic jams since i have used the device. It is far Superior to the three year older Garmin that i replaced.

Pros: Life time Map & traffic updates. Shows how the exits look with a split screen.

Cons: No blue-tooth to connect my phone to. The volume is not loud enough to hear over radio or car stereo.

Speed Limits: As you travel along a major road, the speed limit is displayed on the screen alongside of the vehicle's speed display. If you are exceeding the speed limit, the color of the vehicle speed indication changes to red. If the highway's posted speed limit has changed since the last map update, you can change the speed limit display on the unit.

Where Am I?: The "Where Am I?" feature gives you instant access to important information in case of an emergency. When you select "Where Am I?" from the menu, you get the coordinates (including elevation) of your current position, plus the nearest address and intersections. There are also buttons to help you locate the nearest hospitals, police stations, gas stations, and roadside assistance. You can also save the location for future reference.

Garmin Locate: To assist you in finding your parked vehicle, the Garmin Locate feature saves your location to memory when you remove the device from the windshield mounting cradle while the device is on. You can search for your vehicle's location using the Last Spot button in the menu.

Pedestrian Navigation: In addition to vehicle navigation, the nüvi 2455LMT can also be useful when walking around town. If you have the optional cityXplorer maps loaded into the unit, the pedestrian navigation feature adds public transportation options as you travel on foot.

trafficTrends: When the trafficTrends feature is enabled, the nüvi 2455LMT automatically records historic traffic data and uses that data to calculate more efficient routes. This information is sent to Garmin when you connect your device to myGarmin (your personal account site on the Garmin website) using your computer. Different routes may be calculated based on traffic trends for the day of the week or the time of day.
