even created the G:\.system\diag\html directory, but still I cannot enable the extra functions.
Anyone here with the 3970LMT who has successfully added the new features?
Can you please let me know if you have the 4.90 firmware or was it something older.
Also, please pardon my ignorance, but how do I know if my 3790LMT is region 140?
I would really like to have the mp3 and video functions enabled.
Thank you so much and best regards to everyone.

As far as I remember enabling features worked with 3490 fw version 3.60.
Not tested with other fw versions by me.
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.

Thanks Catymag.

I did read everything from the beginning of this thread.
downloaded every files (which i am thankful that most of the files are linked by other members)
and did exactly eveything step by step...

but my 3790 didnt have the extra features.

im thinking the latest firmware doesnt allow it anymore.
not unless someone can prove me wrong otherwise that they have a 3790 ver 4.90
with working extra features

Thanks again.
