RGN Tool is patching firmware 5.0 correctly. I would expect it enable features.
I tried Turboccc 's rgn tools to patch 5.0 firmware to enable 3D, ASR etc with no luck. Anyone know how to patch the new firmware? Thanks.
RGN Tool is patching firmware 5.0 correctly. I would expect it enable features.
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, 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!!Code:Please Login or Register to see the links

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
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
Updater.exe shows the previous version while flashing.
Your Nuvi must have had 5 previously.
The difference between stupidity and genius is that genius has its limits.

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

darn.. I guess there is no way that I can downgrade the firmware to 4.90 anymore right?
