3D buildings (gmap3d.img)



3D buildings is rather self explanatory – the unit will superimpose a 3D image of the buildings in the vicinity of your position when the unit is in routing mode, so you can at least see/visualise the landmarks around you, rather than at present, where there is nothing to tell you whether you are 100% on the correct road/lane/street or not. The picture best illustrates this idea.
Copy it in your nuvi's \Garmin directory 
or new devices in .System hidden directory

Compatibility: Nuvi 7x5 series , the 3xxx series and 2xxx series 
In 3xxx and 2xxx you can put it also in sd/Map folder with its name gmap3d.img



Foursquare 

 

Foursquare POIs 
Foursquare .img 
Now, when you search, the most relevant Foursquare result appears at the top of the list. It’s an easy way to discover new and popular restaurants, shops and more.
work in 2014 nuvi Advanced Series (25x9 26x9 27x9 2589 2559 2579 2599 2689 2789, and in nuvis 58, 57, 67, 68)


Lane Assistant 

If multiple lanes are to be encountered on your next turn, the Next Turn arrow (single arrow in the green section at the upper left) turns into multiple arrows indicating the available lanes at that junction. It is at this point when the Next Turn indicator (single arrow) turns into the Lane Assist indicator (multiple arrows). The white arrow(s) indicate the lanes you should be in to complete the maneuver while the gray arrow(s) indicate the lanes you should not be in to complete the maneuver. 

Lane Assistant files are part of City Navigator .img file.

Junction view (JCV)

junction view shows the driver which lane on a multi-lane road to take after turning. As we know, modern roads have more than one lane – and being in the right lane can save your life preventing accidents. 
Right on the display you will see realistic road signs with arrows showing you exactly how to navigate the exit
See the screenshot below for junction view .

Bird's Eye Junction View

Commencing with the 2012 'Guidance 3.0' models (34x0 and 35x0) Garmin introduced Bird's Eye Junction View which shows a '3D' representation of selected upcoming junctions just prior to the PhotoReal Junction View. The feature has been extended to all models in the 2013 range except Nuvi 42 & 52.

See this post for an explanatory video. 

Bird's Eye JCV compatible models: 34xx, 35xx, 24x7, 25x7, 27x7.

Time zone map (gmaptz.img)



Save gmaptz.img in the Garmin folder on your device or in sd\Maps

Garmin will automatically determine your current time zone. From your location, it will calculate which time zone you are in, thanks to a small map file in the unit's memory. This is a nice feature if you frequently change time zones, because your GPS's time will update automatically.



ASR-files 

"SRX+ASR"/Voice recognition files (Automatic Speech Recognition)





ASR files must be in .System folder in an ASR Folder 

Speech recognition makes navigation safer and easier than ever. Now it’s possible to keep both hands on the wheel, tell nuvi what to do and where to go, and you’re on your way to stress-free travel.
Once activated, the user can effortlessly manipulate controls by speaking the words that correspond to buttons that are on the touchscreen display, so that almost any common task can be performed without ever touching the unit.
For the ultimate in safety, a driver at any time speak the phrase, “where am I?” and their device will display its exact latitude and longitude coordinates, the nearest address and intersection, and the closest hospitals, police stations and gas stations. Speech recognition can also be used to search for addresses as well – all hands-free, from start to finish.

 



G2S&.db :NuRoute technology&trafficTrends



NuRoute technology with trafficTrends historical traffic and myTrends G2S (GarminAdjacencytoSSID) and .db files

Experience nuRoute™ Technology with trafficTrends™ and myTrends™ 
With trafficTrends™ and myTrends™ no subscription are necessary, no added costs, your nuvi GPS just does it.
With myTrends, when you save your regular destinations in your “Favorites,” your nuvi Garmin will, over time, begin to figure out where you’re going even without your telling it! It provides time of arrival and relevant traffic information. So whether you’re driving to and from work or a regularly scheduled weekly event, your Garmin Nuvi will help you get there on time.

Example of myTrends:

Press the information bar at the top of the map screen in order to display alternative routes if one is available. Here you can press Go! to activate a route to your myTrends destination:

Once you press Go! the unit will begin providing turn by turn

With trafficTrends, your nuvi Garmin GPS automatically learns daytime trends for traffic flow to improve your routes and better predict your estimated time of arrival based on time of day and day of week. And you get free trafficTrends™ updates every time you connect your device to myGarmin.

It displays special routes or information depending on the activity chosen by the user, differentiating between pedestrian activity cycling activity, hiking etc.
To see named trails in Basecamp and in gps you have to add in .img part n., if missing in .img, read this post
and you can simply use ImgTool up to v1.8.1 to do it.
Part n is the name of SQL db file.
A summary of what users discovered to get this info:
