Would you save the GCD after patching? You must have new date of GCD file after it. If date is as for original you do not save changes!

I just got a 3760 LMT today from Costco in Canada, I tried to use the method post by Turbocc to conver it to 3790 functionality, however, it doesnt seem to work. After the flash, I still dont see the voice command bottom, and I dont have any 3D image as well. I download the gcd file from

Code:

, however, it seems to be the 5.00 version even though the file name is (4.90).. because after converting th file to RGN and using the updater.exe, the file being updated is listed as ...5.0 during the process. Is that why this method no longer works? I really dont understand why this process doesnt work on my unit, please help!!

I downloaded the file from your link and it's 4.90 as you can see in RGN tool


To patch use RGN tool:Menu/tools/Nuvi 3790 patch

Yeah, that's what I saw too. But when I load the rgn file with updater.exe, it becomes 5.0 ..even during the update process, it says nuvi ...5.0..

Updater.exe shows the previous version while flashing.
Your Nuvi must have had 5 previously.

Or you gave 5 gcd in your unit and nuvi flashes it ,may be it flashes both ,one after the others.
