New Garmin units no longer say "recalculating route" when you deviate from the set course it lays out for you. They supposedly just begin to give you new directs based on the direction you're then heading in, to steer you back to your destination. In the case of this model however, I've found the "quiet recalculating" feature to be less accurate than Garmins I've used in the past. In my well-established Atlanta neighborhood when I deviated from the planned course, it said nothing. I could see the purple route to follow, went in the opposite direction, and the Garmin remained silent with no new route shown on the screen as well, until I was perhaps nearly half a mile off course. At that point, it finally kicked in and started to take me back on course. On the flip-side however, my Android phone using Google Maps, and my older Mio brand GPS immediately recalculated the route once I deviated, and steered me back. While in a different section of town, when I deviated from a main route, it tried to get me to drive through a subdivision of homes and do a U-turn to go back, instead of recalculating a new route forward (even though I had the U-turn option turned "off"). The Android and Mio units rerouted me forward without trying the U-turn. This I'll point out, is after a system reset and update via the computer (which was recommended by a Garmin employee via support email).
The point is this: You're most likely NOT going to get lost (well, badly) if you use this unit.Read more ›
-Very fast user interface compared to the 265wt.
-Lifetime maps. Cannot emphasize this enough. Buy the LM version of any of these units. Buying new maps later become very expensive.
-Website and software allow installation of additional navigation voices, and "vehicles" including Dora the Explorer, most of which are free.
-Screen is more sensitive and brighter than my old 265wt, with better viewing angles. These aren't IPS, capacitive touchscreens, but they are very functional. There are some complaints about how this unit isn't viewable in direct sunlight. But I live in southern California and have no such problems. Works fine. It may be different if you are walking on foot with these, but these are meant to be used primarily in a car.
-Connecting unit to the computer allows you to "send" navigational points, "Favorites", directly into the unit from Google Maps.
-Lane assist features, which tell you which lane you should be in, are now standard on these basic units. It's a great feature that used to only be on the high-end units.
-Audio for navigation is audible, I had no problems with it.
-And of course, text-to-speech is now available on the cheapest units from Garmin, specifically this one. You can get more voices online.
-Still no way to manage "Favorites" on the computer directly. Creating, deleting, categorizing them. Most of this must be done on the unit itself.Read more ›
The NÜVI 40LM includes a lifetime maps subscription. I have no idea how many updates will be offered over a lifetime of a typical GPS navigator but my NÜVI 660 was seriously out of date and I refused to pay the fee for a "patch."
Features I've come to consider "must haves" on a GPS are:
1. Accurate maps with an easy to use interface
2. Lane assist
3. Speed limit display
4. Junction view
The NÜVI 40 incorporates all the above and I found the 4.3" screen a nice compromise between portability and readability.
Thumbs up to Garmin for giving us a useful entry-level automotive GPS navigator at a budget price.
Oh and by the way the free map updates take about 4 hours to download :(
Here's a cut and paste from this webpage. Good luck when this happens to you on the road....
