The video player can use files other than MP4 such as WMV. Additionally, i recall AVI is also supported. Certainly MP4 files must be H.264 codec and all types of files must be 720*480 resolution or they won't play - or perhaps that's only a maximum resolution and they can be less, just not greater pixel size.

Thanks for your explanation, I'll try it. Surely that must be it.

(ii) the device can still READ it or the XML would not be rewritten properly on re-boot.

As i've said before, if there is 'poisoned' data in 41 from your previous firmware manipulations, and there most likely WILL be, should that be accessed by the device in the future it might at worst 'kill' it and it'll never power on again, or it might just cause an annoying glitch where it'll freeze or re-boot spontaneously or it'll even soft-brick itself. To check whether it's also being successfully WRITTEN TO you'd need to change something obvious and re-boot to then re-compare the old and new XMLs.

I have done the tests and it does write well. I have modified the data that I frame in red in the image in the GarminDevice.xml file.

Afterwards I rebooted and it was overwritten as it was at the beginning, in the image I frame it in green.

Thank you very much Neil, now the help works. It is clearly confirmed that the files in the help folder of the nüvi 3790-37xx are not compatible with those of the nüvi 34xx.

Everything is almost working correctly now. I have seen that the language guide does not work, a screen appears that says: The Language Guide is not installed.

Is there any package or update to make it work?

Greetings;
