Hello good afternoon to everyone. I have a nüvi 3790 that I upgraded and screwed up. Of course I didn't backup NV region 41 before updating it. I was able to recover it with Cure-tool but I have lost the usefulness of voice commands. It has also become a 37xx instead of 3790. I have read everything about this topic on the forum, I have done everything I could, but I have not been able to turn my nüvi to 3790 or the voice commands. I have also not been able to transform it into a nüvi 34xx, when the updater connects in preboot mode to flash the 34xx.gcd file, it tells me that they are different HWDI and cannot load it.

Could someone help me recover my nüvi 3790?

It works well, but the truth is that without voice commands it's a pain.

Thanks to everyone beforehand.

Greetings;
Choco
