Thread: Garmin Map Pilot for Mercedes-Benz cars

i made an sd card from the img. the map program loads but cannot unlock maps. if i remove the map files it loads not saying anything about the maps. if i have an unlocked img file from other garmin's is there a way to convert it to NDS format?

word this work?

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

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?

oh ok, tried that, didnt work. was hoping to create the .unl file to the sd card and not the unit to see if that would work. i read somewhere someone had done this for another garmin gps but cannot remember where i read it.

Yes, I tried it as well, but those gma files seem to be certificates for those 12 map files, which must've been generated by Garmin, together or based on those unl files? Or something like that? I presume they're linked in one way or the other...
