Thread: Garmin Map Pilot for Mercedes-Benz cars

In root.nds there is a table called 'productDbTable'.

The field 'DataModelVersion' could be the MapID, in my Europe 2014 (2.3) map version it is 6095.




Maybe some could try to generate .unl files using that ID.

Found FID

Spoiler: fid

Thats great news!

Can you enlighten us in how you found it?

I'm just starting to learn how about all this stuff but would be interested in understanding it.

That could mean we would be able to generate *.unl files for any given CID. Still leaves us with the *.GMA piece I blieve.

So... with FID and System ID, with Garmin kgen 1.5 you could generate .unl files...
But how about the gma files? Those need to be generated as well from somewhere?

Great work so far, I think we're almost there?

Problem is that in regular device kg don't work after fid greater of 2200, so i think that also here will not work.
If we have FW update file we maybe can found out some data that we need to figure out how this unit work.

p.s.
Where is stored unl and gma files on non used SD?
Unl files is stored in map E1, E2, etc?

Well assumingly

NaviPnd.dll and navi_pch.exe on the SD card are the actual navigation software, maybe this can be debugged (looks like some kind of embedded version of Windows)

On a virgin SD these files are stored under the /Garmin directory.

called

EU-E1.gma
EU-E1.unl

EU-E12.gma
EU-E12.unl

Well, I can generate unl files like this:
Fill in the system id of the mercedes nav system in Unit ID, then for each map you can generate the unl file...



But then, of course... what to do with those gma files...

I guess that would need to be the CID of the SD card you would like to use.

do you know how to get the CID of the card?

CID of the SD card? Has nothing to do with it I think?

I can perfectly generate the unl files, just using the ID of my Mercedes navigation app (which you can find in the settings menu in the navigation app in the car), combined with the custom mapset for each of the 12 map files.

I don't know where you'd use the CID of the SD card?
