In first post of this thread you have tutorial how to go in pre boot on your device and also how to use updater and rgn file.

RGN Tools:
1:rgn tool';s read me file said: "to start your GPS
in service/pre-boot mode" , i tried two different method (1., to hold the power button, and 2., touch the right bottom corner of the screen and hold the power) but nothing,
2: i backup the remote sw folder with two gcd files, it is ok????

sorry, but i can not understand anything like it,
it the first post there are a different way, with different links, and files, S:SSSS
can someone tell me what i have to do exactly?
lolypop: i tried to upgrade with your lat link - no solution, i tried to do wit the files from the first post - same :SSS
This should work for you, but it's untested as i don't have a 3750/3760 to try it. I've converted the patched rgn file to a gcd file and changed the Software Version to 501 from 500 which should allow you to update via microSD card.
Spoiler: Download and Step by Step instructions
IMPORTANT: Before you do any firmware flashing ALWAYS backup your nonvol region 41 [see first post for link to tutorial]. Make files back up of the internal memory and then clear nonvol also as per guide in post #1 . Do that again after the flash as well.

In first post is writen how you enter in pre boot mode ( where you must add finger on screen ), so first look picture in first post for pre boot.
Now open updater.exe in pack that i send you and add dot beside usb
Now connect device to Pc and add finger in left uper corner of screen OR little abow letter G and you will see in updater window beside USB your device
now click on button OK and whait that procedure is over
When update is finish your nuvi will turn off and back on again and you will have enabled feature on your device.

I guess you haven't followed with care this:
posted here:Before doing anything Drag&Drop the rgn file you want to flash to your device (it can be a normal firmware file or a file rgn extracted with RGN Tool or you got from Garmin ) in Updater.exe and it will open in your desktop.Tick USB device
[Only registered and activated users can see links. ]
You have few seconds to flash rgn , or nuvi reboots.Updater will display your nuvi model in it's window, this is the moment to press ok
You have to navigate to get to the good.
Galaxy S5 Kitkat 4.4.2 / Nuvi1200->1250 / Nuvi3790T->34xx / Nuvi 2200 / Nuvi 66 / Oregon 600
You DON'T need rgn tool if you use pack below.
Do like this:
- First download and extract this on desktop of Pc
Spoiler:
- now drag/drop rgn on updater.exe
- add dot beside USB in updater window
- connect nuvi with cable to Pc and when you see garmin logo quick press little above G and hold finger there
- in updater window you will see writen Blade series beside usb
- now quick click on OK button in updater window ( you have only 10 sec to hit OK button ) you must still hold screen
- after updater say that is finsif you can release finger from screen.
Thank you for everyone!
it seems like ok, (but i did not do backup:S)
i did it with lolypop's solution,
i could not connect my device to the rgn-tool, to save backup, it is really strange for me, i did everything step by step, i don't know that it is important or not.
Do you have Garmin USB drivers installed?
