What Files supports my Garmin Device and which Files I should update?

Often, indeed almost always, on the occasion of the release of a release of Maps the Forum is overwhelmed with questions (and therefore of Post) of the type:

• My Nuvì xxxx supports JCV? If Yes, what type?
• Can I install in my Nuvì xxxx 3DBuilding Map?
• Where to copy Maps? In which folder?

All of this information, and consequently many answers to your questions, are contained in the File GarminDevice.xml of your Device.
We learn to read it and understand it.

Where can I find GarminDevice.xml?

• Connect your Device to PC via USB port
• Open \Garmin folder of your Device and you will find the GarminDevice.xml
• Although it is basically a Text File, it has a "formatting" XML. If you open it with a normal Text Editor (like Windows Notepad, so to speak) you will probably see a "tangle" of unstructured characters.
• The best solution, unless you use an Advanced Texts Editor (like Notepad ++), is to open it directly in the Browser (FireFox, Chrome, etc ...).
  Browsers have integrated the XML PlugIn so the various "sections" of the File will be much more readable.
• Use the "Search" function of the Browser (CTRL + F) to find the Strings in the File

Model, HWID, ID and Firmware release
One of the first sections of the File is the one that contains the Device Information, ie:
