Thread: Garmin Map Pilot for Mercedes-Benz cars

In case anyone is following along, or would like to try this themselves. Toss the .dll into IDA Pro, and go to this memory location:

.text:109AE4A0 bt UnlocksMatchCard

(I named the branch destination "UnlocksMatchCard")

Change that "bt" to a "bra" so that it always branches, and you should be done.

If I made a patched version, would anyone be willing to test it?

Hi FrankRizzo!

I have a mercedez benz C250 here and I can give it a try. I downloaded the entire "piotrscs" files, and the other 24 files which should be located at root directory.

The problem I have is that I don't have a 16gb SD card to test it, so I will order one to make tests.

About the maps, I have an unlocked map (img file) for my country which I use on another garmin devices, do you know if there is some way to remove the europe maps and replace them with my one?

Thanks!

I would be willing to try too. 2015 C300 with Audio 20 and touchpad.

I'm also willing to test it.

I'd love to test it, and I do have SD card...
