4 out of 5 eggsgreat for what it is.

Pros: Price, and it no longer says RECALCULATING. Still easier to have a standalone GPS than a smart phone, especially at this price.

Cons: By no means top of the line, be aware of that.

Other Thoughts: Replaced an older Garmin in a car where the user only connects it for longer trips. If you plan to use it everyday think about stepping up to a better unit.

1 out of 5 eggsUseless! Get something else or use a phone

Pros: The touchscreen works well

Cons: And you're gonna need it, because it doesn't have voice recognition for spoken destinations. I knew about that, but thought that it wouldn't be that much of problem, until I found myself having to pull over somewhere to type in a new destination. Get one with voice!

Besides that, after typing in a destination, it searches for about 5-10 minutes and often says 'no results found' or doesn't find a specific name of a location, for example, it finds stores in a list and will have a store that is 20 miles away, when I know there is one a few exits away, but it doesn't show up on the list. Also, times when it has worked, it gives me a weird route. Granted, that also happens sometimes with Google Navigation in Android.

4 out of 5 eggsGood upgrade from nuvi 205

Pros: Large screen
Bright screen
Clear voice directions
Split screen at major intersections

Cons: Battery live can be a bit longer
Screen sometimes is slow to refresh
Question it's logic on the routes is sends me on.
Touchpad doesn't always work on the first try.

Other Thoughts: After reading all the reviews, I was a bit worried when I got the nuvi 40LM as a gift.
But after a test run home & a trip to Baltimore, MD, it got my to the desired destination without any major problems.
Good GPS for the first time buyer, or someone looking for an easy to use model.

1 out of 5 eggsAnother Disappointment

Pros: If you never care about updating this product, you'll be alright.

Cons: Another failed update, I purchase the Nuvi40LM because after updating the firmware in my Nuvi1490 I was unable to update the maps. After this purchase, I updated the firmware on the 40LM and then the 2.6GB map software with a message that update completed successful, not so, the message on the nuvi40LM when attempting to use was no map data available. This was my third nuvi and updates to firmware and maps has always been time consuming and not reliable.

1 out of 5 eggsWorst Ever - Do Not Buy

Pros: NONE - Oh - cute little voices and icons you can download.

Cons: Major flaw in routing. Takes off major safe highways onto dangerous rural roads and mountain passes. Refuses to stay on major highways.
Has choices for shortest time, or shortest distance, (off-road ???). Has no option for most use of highways (like another well known brand).
My family has been taken on dangerous routes. We got to where we had to check maps first, then only use the Garmin in the last few miles or blocks as it has serious problems over long distances.

Other Thoughts: Have spoken with tech support numerous times. The Garmins we purchased always trying to get us to exit and takes us on less traveled often impassable back roads. Or slow moving side streets.
Ultimately increasing the time or danger levels. If you are a delivery driver working in your own small neighborhood then this might work. And poorly at that. Long distance or to unfamiliar places - NO WAY.
