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.

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.

It would be great if you guys can also post instructions for non techies

Hi i Have a question, i need to download the torrent file because i have downloaded and need to download the 5 parts stored on multiserver too? or are the same files?? thank you..

About the GArminDevice.xml... Got it. I had a little error in my GarminDevice.xml:

I thought I had to use 006-B1063-01, but my hwid is 1101 so I should keep to 006-B1101-00. Also, the description is "3790" and not "3790T". It was right the first time, but had so many issues that I changed it to 3790T. The rest can stay as before I think, but adding some missing 3D map will probably help.

In the end, I just kept the .xml file and deleted everything else. Nothing was happening, si I changed all Major version to 0. He! He! myDashboard resent the GCD. Then, change back the GCD version to 2.50 and re-update again. All voice files, keyboard files and so on re-appeared. Now, I am back with the map update (which will take forever again).

Note: I am also doing all of this on my flash card and not the nuvi. I'll post a newbie guide if this ends well.

I like you post. I spent part of last night trying to to just that. I have a 3750. I changed the GarminDevice.xml to impersonate a 3790. I was able to register it in My Garmin and download the free maps, but for some reasons, I cannot get the 3D Building maps. The myGarmin Agent does not recognize the device enough to add all the missing files either.

Today, I tried also to change the prodkey.bin files in the .System folder without success. The myGarmin Agent does not see the device as valid for update and suggest the WebUpdated instead (which does not work either). I am probably very close. I just read your post and now I am convinced it should work. I am missing something.

What I have done so far:

- Changed Garmindevice.xml to add a valid ID for the unit (an unregistered one as well!).
- I updated the maps (I have seen all that went thought the %temp% folder EXCEPT no gmapd3d.img which was the point of the exercise). I did this twice without success and it took part of the night!

I like the idea of using a USB key. I would appreciate a lot if you could provide more information about what is really needed in the folder tree.

I am trying to convert the 3750 into a 3790. I know it will miss the voice command (except if I can solder a microphone there) and the bluetooth, but 3B building should work.

Thanks in advance,

Turbo

Edit: now that I think of it, I may have seen the gmap3d, but thought it was one I d/l from the web... I did too many things at the same time.

Edit2: After more research, it seems myAgent refuses to update because some information from the 3790T is not included in my GarminDevice.xml. Maybe a missing file specifications or another similar definition. If anybody is willing to send me a GarminDevice.xml to turboccc at hotmail dot com, I could share my results with all of you. Be sure to remove your ID from the file. Put zeros instead. Many thanks.

@turbocc and others

This is some further data for those who have read my [Only registered and activated users can see links. ] & [Only registered and activated users can see links. ].

You will find a attached "GarminDevice.xml" file for a nüvi 3790T Atlantic version at the end of this post. Unit ID set to 1234567890 and all 25 character codes are based on 1234567890.
Put the "GarminDevice.xml" file in the "[X:]\Garmin" directory as "[X:]\Garmin\GarminDevice.xml".


If one needs the file structure for a nüvi 3790 it's possible to create a "md_3790.bat" file with the content in the code section. Run from root in USB mass storage device.

Some explanation for those who tries to use Garmin Map Update to download complete set of additional files with 3D, JCV, G2S, DB etc.
The requirement is that you have a valid map update at myGarmin to download with a valid product code. The only thing is that a user with nüvi 2xx, 5xx and likewise may fetch the extra files for Junction View, trafficTrends, nüRoute, 3D buildings to share with the ones who can use those files.
No succes at all expected for those who tries without a genuine valid lifetime or onetime map update and a active product code for their specific unit ID.
