I'm not sure, but I think enabling features by using xml files doesn't work with nuvi 3790. Only by patching (modifying) region 140.
The whole device memory is divided into some regions. Region 140 is a part of the whole system.
Somewhere in this forum is a topic about executing code from SD card. At this topic is explained about regions.

Thanks Voyager56.
Now I understand Region 140.
The FW version is also what Im thinking abt, maybe the latest one doesnt allow mod anymore so Im thinking of
downgrading to 3.60 as you have mentioned. I tried the patch mod but didnt work.
