Thread: Enable 3790 features on your 3750/60

(Sorry for double posting, but I think this is worth it!)

Gentlemen! Today is your lucky day if you have a 3750 or a 3760. I found a way to enable the Contacts, Calendar, 3D Terrain and Building like on the nuvi 3790. ASR appears and is functional on the 3760, but it does not work on the 3750 as there is no microphone installed. See the table below for the list of features that can be enabled for each GPS per firmware region.

[Only registered and activated users can see links. ]

To enable those features, use RGN_Tool.exe. Load your firmware in RGN_Tool, patch it using the Tools->Nuvi 3790 Patch. Save the modified firmware and flash. Make sure to use the right boot.bin with the correct HWID. All previous rules apply.

RGN_Tool v0.94: [Only registered and activated users can see links. ]

Post feedback here in this thread.

Edit:

With 3760 US firmware v4.50, I am told that ASR is enabled and WORKING! Seems like the microphone is installed which is not the case for the 3750 US model.
