If you select the "Install to Device and Computer" option, you will then be updating your Computer (MapSource) AND the Device.
The complete "img" folder (that is downloaded to the temp folder) is the same for all Computer/MapSource downloads, regardless of the Device model or type.
If you want to save the MapSource installation files, they are saved in the %temp%\img directory.

As, once the Device update is finished that temp "img" directory is automatically deleted.
As explained in my [Only registered and activated users can see links. ] you have the option to save ALL files. Files are downloaded one by one as it process the manifest file. There's also a separate file check procedure that controls if downloaded files have the correct MD5 hash code.
Example of RMU download manifest file for CNNANT 2011.30:
Code:

MapSource installation and GMAP files are stored at "%TEMP%\IMG"
ASR, JCV, gmap3d.img etc. are stored directly to "%TEMP%".
ALL files remains after the download are finished if you ticked the option to keep the files.

Editing the "GarminDevice.xml" file with another PartNumber (with matching last SoftwareVersion number, MapUpdater probably wants the unit to be updated before downloading maps) makes the downloader to download all suitable files for that device type. If you have a nüvi 200 you can impersonate a nüvi 3790 and download the nüvi 3790 files instead.
I'm not using a Garmin GPS at all for the download, just a USB stick with "[X:\]Garmin\GarminDevice.xml" and the appropriate directory structure for the GPS model. Just needing the product key (or prodkey*.bin file) for the combination of Garmin unitID & map product.

All that happened during the map update with Garmin Map Update is saved to a log. Take a look at "%APPDATA%\GARMIN\Map Update\SetupLog.txt". You will find URLs and data for downloaded mapset and additional files in the log.
