found it, just USB My software currently does not support this.

The interface itself does not matter, it is all about the protocol it talks to your PC. What interface is this? What protocols does it use? Is it programmable and which microcontroller is soldered? Or is it just USB brdige?

Hello Mattias, welcome to the board! What are your skills and targets regarding satnavs?

Saw the link at top?

How did you start it? In the early days i've completely decompiled the Flash using IDA Pro. Maybe Claude or Codex can do this without the need of a decompiler? Naming strings and CAN/OBD/UDS IDs and bits/bytes might help to find the sources. Best would be to habe a way to get the full source code ba...

Excellent, give me some time to fully understand and reproduce your findings.

This is a very neat and interesting project, i'm curious to get deeper into details. Can you elaborate more about the simulator and how found find the entrypoints to inject own code and how you compile that code for the MAC?

Hi, i did the same also for other LIN modules like battery sensor, alarm module, BCM. Me and AI developed a reverse engineering tool, which might be a benifit for you as well? https://github.com/igittigitt/esp32_lin_sniffer

I'm investigating in the interior-motion-sensor. It is LiN connected to BCM ("LIN 2").

Looks good, where did you bought it? I've recently created my own tool for CAN and LIN, based in ESP32-C6, really cheap.
