Some of the Garmin menus are buried really deep ...

This is at: Menu, Menu, Setup, System, Menu, Software Version

You can check your Software Version here (though I would think of it more as Firmware) and then check the list of Garmin Updates for a newer version for your particular model.
Make sure you only download and apply updates for your particular model number.
For Windows users, its easy to download the file and just run it while your Garmin is connected to the PC.
For Mac users, you'll need to work through Garmin's recommended procedure via Support and Updates on their website.
There are sometimes version updates for Mapsource too. Always check the changes list in case some useful functionality is about to be removed! - it's not unknown!

This is at: Menu, Menu, Setup, System, Menu, Card Info

I wonder how many people have found this screen??
It just shows the size and space available on your Micro-SD card (only applicable to Garmin 'x' models of course).
In this example, it's a big card - 2Gb - the maps take up slightly less than half, and a few stored tracks account for a few Kilobytes. There's still over 1Mb free even though the maps cover all of UK & Ireland, France and Switzerland and quite a lot of the rest of Western Europe.
So I could, if I wanted, store some MP3 files on here, or maybe even use the card as emergency spare in a camera, when its not needed for GPS duties (being careful not to reformat it of course!).
Note that the internal memory of the GPS - where Waypoints, Routes and Tracks are stored, is nothing to do with the SD card and doesn't show up here.
However some recorded Tracks can end up on the SD card - see the next panel down for more information about this.

This is at: Menu, Menu, Setup, Tracks, Setup, Data Card Setup

In here you get the very useful option to Log Track to Data Card.
I recommend turning this on. Again this is only applicable to 'x' models.
Your Garmin then just automatically saves each day's tracklog to the Micro-SD card, as a .gpx file, and as you see the filenames simply reflect the date the file was written.
These files are much more complete than the tracks you get when opting to Save Track - because Saved Tracks are downsampled to 500 points and lose their timestamp and elevation data into the bargain.
The tracks auto-saved as .gpx files are not subject to this 500-point limit, they are complete in every respect.
With a decent-sized card there'll be room for loads of these gpx files - even though your map is stored on the same card - as you see here the bar-graph shows this card as less than half-full including map, and each gpx file is only a few Kb.
Delete All does not delete the map by the way - only the stored .gpx files. Phew.

Retrieval of this track information is another matter!
The only way, is to connect your Garmin as usual but then configure it as a Storage Device
This is Menu, Menu, Setup, Interface - you can now access the contents of the Micro-SD card using a File Manager such as Explorer.
Alternatively, just remove the card and put it in a card reader - you'll need a Micro-SD to SD adapter for this, most Micro-SD cards are sold with one as standard.
The resultant .gpx files can be opened in Mapsource or most other mapping programs.

This is at: Menu, Menu, Setup, System, WAAS

On some units this is marked WAAS, on some it is marked WAAS / EGNOS as shown here.
For cycling purposes, I recommend leaving this disabled.
WAAS is a bolt-on GPS system that has been added to improve the accuracy of the main system - it uses additional satellites and ground stations and generally achieves about a 5x increase in accuracy if you take a 'spot' position. However WAAS is only useful in North America.
The European equivalent has been developed more recently and is called EGNOS. It turns out that the protocols etc are exactly the same as WAAS and, if you have a GPS or Satnav that can use WAAS, it will also be able to use EGNOS even if there is no mention of the newer system in the menus.
There are similar localised bolt-on systems in other areas such as the Far East, but I don't know whether they too are fully compatible with WAAS, or not.
I would leave this disabled because it's a slight battery hit (around 15%-20% reduced runtime), that the most obvious benefits are only seen shortly after switch-on, and that increasing accuracy from circa 10m to circa 2m is just pointless from a cycling point of view.
For walkers or geo-cachers, in an area where there is coverage (N.America, W.Europe), I would certainly enable it. (NB you can tell when it's working by looking at the Satellite Page, where 'enhanced' satellites will show a tiny D in the bar graph.)
