Hi,
I am also interested. Can you please point out the topic in garniak where PouchX has hinted about changing NV.
Many Thanks,

Why do you think we need to modify NVram to flash Nuvi 3790 to SG/MAL or CHN latest firmware?
Can you give a link to topic on garniak.pl about NVram modification? I can't find it with google.
A ja użytkownikom 3790 proponuje znalezienie kolegi z 3750/3760/34xx i zrzucenie zapisów regionu NV.Code:Please Login or Register to see the links
A następnie wrzucenie tego do swojego 3790.
Wcześniej zalecam zrobić kopię/zrzut NV swojego Nuvi aby później móc mieć tego Nuvi co się miało.
Po przeróbce 3790 na 3760/34xx możemy sobie testować dowolny firmware SG/TWN/CHN.
Problem z wolnym odświeżaniem map rozwiązujemy poprzez zmianę adresowania (i ewentualnie wielkości) cache'a.
Podpowiedź: "Czytać boot loader/loader...a stanie się jasność".
Podpowiedź 2: Całość operacji ( po wcześniejszej analizie HEX..itd.....) wykonywana jest z karty SD/microSD
Podpowiedź 3. IDA Pro i "loading address" też się przyda.
Podpowiedź 4. "Loading address" jest w oryginalnym .gdc/.rgn. Offset'y znajdziecie sami. Użyjcie HEX-value-revers

Nuvi 3490 supports new features (files):
D3175030A.sid InstaSearch Size: 173422
D3413020A.db CountryStateSearch Size: 33500
D3176030A.sid AddressSearch Size: 296000
D3414020A.sid FastRouting Size: 164063
Code:Please Login or Register to see the links
Analyzing GarminDevice.xml from Nuvi 3490 I discovered some interesting things.
Some new features like InstaSearch, AddressSearch, FastRouting, which are related to SID:
</DataType>
- <DataType>
<Name>InstaSearch</Name>
- <File>
- <Specification>
<Identifier>INSTASEARCH</Identifier>
</Specification>
- <Location>
<Path>.System/SID</Path>
<FileExtension>sid</FileExtension>
</Location>
<TransferDirection>InputOutput</TransferDirection>
</File>
</DataType>
- <DataType>
<Name>AddressSearch</Name>
- <File>
- <Specification>
<Identifier>ASG</Identifier>
</Specification>
- <Location>
<Path>.System/SID</Path>
<FileExtension>sid</FileExtension>
</Location>
<TransferDirection>InputOutput</TransferDirection>
</File>
</DataType>
- <DataType>
<Name>FastRouting</Name>
- <File>
- <Specification>
<Identifier>PPD</Identifier>
</Specification>
- <Location>
<Path>.System/SID</Path>
<FileExtension>sid</FileExtension>
</Location>
<TransferDirection>InputOutput</TransferDirection>
</File>
</DataType>
-----------
But what is different from other devices is:
- <DataType>
<Name>trafficTrendsv3</Name>
- <File>
- <Specification>
<Identifier>HTF</Identifier>
</Specification>
- <Location>
<Path>.System/SID</Path>
<FileExtension>sid</FileExtension>
</Location>
<TransferDirection>InputOutput</TransferDirection>
</File>
</DataType>
- <DataType>
<Name>CountryStateSearch</Name>
- <File>
- <Specification>
<Identifier>CBX</Identifier>
</Specification>
- <Location>
<Path>.System/SQLite</Path>
<FileExtension>db</FileExtension>
</Location>
<TransferDirection>InputOutput</TransferDirection>
</File>
</DataType>
-----------------------------------
Looks like Traffic Trends now are not related to sqlite like it was in other units:
- <DataType>
<Name>trafficTrends</Name>
- <File>
- <Specification>
<Identifier>HTF</Identifier>
</Specification>
- <Location>
<Path>.System/SQLite</Path>
<FileExtension>db</FileExtension>
</Location>
<TransferDirection>InputOutput</TransferDirection>
</File>
</DataType>
-------------------
Also SQlite is now "CountryStateSearch":
- <DataType>
<Name>CountryStateSearch</Name>
- <File>
- <Specification>
<Identifier>CBX</Identifier>
</Specification>
- <Location>
<Path>.System/SQLite</Path>
<FileExtension>db</FileExtension>
</Location>
<TransferDirection>InputOutput</TransferDirection>
</File>
</DataType>
---------------------------------------
In SQlite folder I have to files: D317400.db and D3413020A.db.
File D317400.db is a well known Traffic Trends file.
So D3413020A.db must be related to CountryStateSearch.
When I remove D317400.db then my Nuvi doesn't show TrafficTrends text at the CNE map.
When this file remains, I have Traffic Trends v4.25.
But then what means this:
- <DataType>
<Name>trafficTrendsv3</Name>
- <File>
- <Specification>
<Identifier>HTF</Identifier>
</Specification>
- <Location>
<Path>.System/SID</Path>
<FileExtension>sid</FileExtension>
</Location>
<TransferDirection>InputOutput</TransferDirection>
</File>
</DataType>
You have to navigate to get to the good.

Yes I know but in your post I didn't found information about D3413020A.db which comes with CNE 2012.30 Unicode for Nuvi 3490.
Caty, is this file included in your SID.part1.rar + SID.part2.rar ?
My previous post was mostly about differences between Nuvi 3490 and some other units.
First of all sid files, but also some news in Traffic Trends. Looks like Traffic trends now are related to D342701.sid but not Sqlite file D317400.db.
